Stage IX2-SFR/IX-MVR

· Before transporting the stage, fix the flexible handle with pieces of adhesive tape so that it will not move.

SAFETY PRECAUTIONS

1. After the equipment has been used in an observation of a specimen that is accompanied with a potential of infection, clean the parts coming in contact with the specimen to prevent infection.

· Moving this product is accompanied with the risk of dropping the specimen. Be sure to remove the specimen before moving this product.

· In case the specimen is damaged by erroneous operation, promptly take the infection prevention measures.

2. If a foreign object is caught during motorized focusing operation, there will be an error in the focusing block and the motorized focusing operation will be suspended.

Recovery procedure

· If there is no error in motorized operation, the caught object can be removed by turning the focusing knob or focusing button.

· If there is an error in motorized operation, the focusing knob or focusing button becomes inoperable. Disassemble the relevant modules to remove the caught object. Replace the relevant modules afterward.

· Turn off the power and then on again. The system will restart unless there is a malfunction in the motor.

3. To activate temporary stop during focusing operation, turn the focusing knob (or dial) on the microscope frame (in either direction) or press any of the FOCUS control buttons ( , , F/C and ESC) (except during PC communications).

When the main switch of the IX2-UCB control box is set to “ I " (ON), the focusing operation starts automatically as part of initialization

(this operation consists of temporary raising and then returning to the original position of the objective).

If any of the operations mentioned above is performed, an emergency stop will also occur. In this case, set the main switch to “ " (OFF) and then “ I " (ON) again.

4. When lowering the objective by pressing the focus button, be careful not to have your hand caught between the bottom of the revolving nosepiece and the microscope frame.

(Fig. 4)

}Set the main switch of the IX2-UCB control box to “ I ” (ON), then press the transmitted light ON-OFF button 1 to ON.

1. Press the light intensity control button 2 to increase the voltage and make illumination brighter.

Pressing the button 3 makes the illumination darker.

2. The numerals to the right of the lamp voltage indicator LEDs 4 indicate the reference values of the voltages.

# The LEDs may turn off (temporarily) when the motor is driven, but the illumination intensity does not vary even if this occurs.

3. The marking 5 is the reference position indicating 9 V, which is the suitable intensity for color photography (using LBD filter).

Light Path Selection

(Fig. 4)

}The light path selector button 6 allows for light path switching between the observation and side port paths.

The selected light path can be confirmed with the LED on the side of the button.

: Observation 100% light path.

: Side port 100% light path (with the IX81S1F-2 microscope frame)

Side port light path 80%/Observation 20% light path

(with the IX81S8F-2)

}The light path to the lower back port can also be set by the manufacturer’s part replacement operation. (IX2-LBPC)

IX81

Fig. 5

Magnification Change

(Fig. 5)

When the magnification selector knob 1 is pulled out, the magnification will be 1.6X. When the knob is pushed in, the magnification will be 1X.

}The 1X 1.6X magnification changer lens can be replaced with a 1X 2X magnification changer lens (IX2-CA2) by the manufacturer operation.

Motorized Revolving Nosepiece

# When the IX81 motorized revolving nosepiece is rotated in stand-alone mode, automatic escape movement of an objective is not performed.

Therefore, let the motorized revolving nosepiece escape once before turning the nosepiece.

The motorized revolving nosepiece can be rotated to switch the objective by pressing an appropriate button on the U-HSTR2 hand switch or a button assigned by the PC.

}When the IX2-BSW software (Ver. 01.03 or later) is started up, the revolving nosepiece escapes to avoid interference with the stage as the objective is switched, and returns to the original position after objective changing.

# It is basically inhibited to attempt to rotate a motorized revolving nosepiece manually.

However, it can be moved to the front and rear by hand only when an oil immersion objective is used and bubbles are produced inside the oil.

Frame Clamping Plate

}This is the module for clamping the microscope frame onto an antivibration platform. The applicable anti-vibration platforms are the following four models.

· 25 mm pitch and 50 mm pitch anti-vibration platforms.

· 1-inch pitch and 2-inch pitch anti-vibration platforms.

For the assembly procedure, see item

on page 58.

4-2 Focusing Block

}The same effect as the focusing knob on the microscope frame can also be obtained using the U-FH focus adjustment knob unit. However, when the microscope is used stand-alone while the cable to the U-FH is connected, the control used for focus adjustment is switched automatically to the focus adjustment knob on the U-FH.

Rotation Direction of the Focusing Knob

(Fig. 6)

· Rotating the focus adjustment knob 1 toward the front (in the direction of the arrow) raises the objective and toward the rear (opposite direction) lowers the objective.

Tilting the Illumination Column

(Fig. 22)

}When replacing large specimens, placing a micromanipulator or replacing a patch clamp electrode, working space can be created by tilting the illumination column.

}Even with the illumination column tilted, the specimen surface will be illuminated, which is convenient for rough confirmation of the specimen location or initial positioning when placing the specimen.

1. Using the Allen screwdriver, loosen the column tilt clamping screw 1 by turning it approximately 11 turns in the direction of the arrow.

2. Holding the illuminator attachment’s upper front side, slowly tilt the illumination column backward. Vibrations should be avoided. Accordingly, always support the illumination column with a hand and tilt slowly and gently. To return the column to its original position, reverse this procedure.

When tilting the illumination column upwards or downwards, make sure not to catch your gingers in the hinge joint.

# The tilt clamping screw should normally be tightened during use. If the microscope is used while the screw is loosened, make sure that the illumination column does not accidentally tilt during use.

When moving or transporting the microscope, always do so with the tilt clamping screw tightened.

# If a heavy module such as a high-intensity lamp housing is installed, always use the microscope with the tilt clamping screw tightened.

Using the Aperture Iris Diaphragm

(Fig. 32)

}In general, the potential resolving power of an objective is fully utilized if the diaphragm is stopped down to correspond with the numerical aperture

(N.A.) of the objective.

}Depending on the specimen, image contras or focal depth in observation or photomicrography may be improved by keeping the aperture iris diaphragm stopped down a little.

In general. a good image is obtained if the diaphragm is stopped down to between 70% and 80% of the N.A. of the objective. Stop further down for less contrasty specimens.

}To check the position of the perimeter of the aperture iris diaphragm, remove the eyepieces and look into the eyepiece sleeves to view the aperture iris diaphragm image and the objective’s exit pupil.

}When using the U-BI90CT binocular observation tube, the aperture iris diaphragm can be observed by setting the turret to position “CT” or using the U-CT30 centering telescope.

Flipping Up the Condenser Holder

Caution when cleaning

When wiping off immersion oil or oil attached to the oil-proof cap, do not press the cap hard. Otherwise, the tip of the objective will retract due to the buffer spring mechanism, causing the cap to come off and oil or water to penetrate into the objective. Take care not to push the cap when wiping it.

Fig. 35

Adjusting the Correction Collar

1. The collection collar is effective with vessels with bottom thickness. (See pages 47 and 48 for the instructions on correction collar objectives.)

When the thickness of the vessel bottom is known, match the scale reading of the correction collar to the thickness of the vessel in use.

2. How to find the optimum position based on image resolution and contrast:

· If the thickness of the vessel bottom is unknown, the optimum position for the collection collar can be obtained by judging the image resolution and contrast. When a satisfactory image is not obtained after focusing, rotate the correction collar to the left and right, refocus each time and compare the images at both sides. Then rotate the collar in the direction yielding a better image, and rotate the collection collar to the left and right, refocus each time and compare the images. Repeat this cycle until the position with the optimum image is found.

Using Immersion Objectives

(Fig. 35)

# Always use immersion oil supplied by Olympus.

}If the objective in use can accommodate the oil-proof cap, be sure to mount the cap.

1. Using a low-power objective, bring the specimen into focus.

2. Rotate the revolving nosepiece to engage the oil immersion objective.

3. Remove the specimen and move the stage insert cut-out 1 close to the objective front lens. Apply a drop of the provided immersion oil to the objective front lens. Place the specimen and rotate the fine adjustment knob to bring the specimen into focus.

# Use as little oil as possible. After gently wiping off the oil on the oilproof cap, remove the cap. Then clean the tip of the objective and areas around it as well as the cap.

# If the oil contains air bubbles, the image will be degraded. Make sure the oil is free of air bubbles.

a) To check for air bubbles, remove the eyepieces, completely open the field iris diaphragm and aperture iris diaphragm, and look at the objective exit pupil (looking like a bright circle) in the observation tube. Any air bubbles can be seen in this way.

b) To remove air bubbles, slightly rock the revolving nosepiece manually to engage and disengage the oil immersion objective once or twice.

4. After use, remove immersion oil from the objective front lens by wiping with gauze slightly moistened with absolute alcohol.

}The same procedure is applicable when using a water immersion objective.

Caution on using the immersion oil:

If immersion oil comes into contact with your eye or skin, immediately take the following action.

For eye: Rinse with clean water (for more than 15 minutes).

For skin:Wash with soap and water.

If the appearance of the eye or skin changes or pain continues, immediately consult your doctor.

}Refer to the provided instruction manual.

Fig. 44

Attaching the DIC Optical Elements

(Fig. 44)

}The attaching method is identical to that for the phase contrast optical elements (page 29 & 30), except that the positioning pin and positioning groove should be aligned when attaching each DIC optical element.

· Align the positioning index 1 on the DIC prism with the positioning index 2 on a turret position and insert the DIC prism all the way into the turret position so that the DIC prism’s frame hits the bottom of the position and the prism’s positioning pin fits into the pin hole. When inserting, push the spring 3 inside the turret slightly sideward. (Fig. 44)

# Be careful not to touch the DIC prism area inside the frame.

# Do not tighten the optical element centering knobs too much, for this may deform the frame of the optical element.

IX81

Attaching the Analyzer and DIC Slider

(Figs. 45 to 47)

With the U-DICT DIC Slider

1. Remove the dummy slider from the revolving nosepiece.

2. Align the index 1 of the U-ANT analyzer and the positioning groove 2 of the U-DICT DIC slider and drop the analyzer into the analyzer mount of the DIC slider. (Fig. 45)

Fig. 45

Fig. 46

3. Hold the U-DICT 3 so that the side with indication faces down, insert it into the revolving nosepiece, and tighten the clamping knob 4.

With the U-DICTS/U-DICTHC/U-DICTHR DIC Slider

}The U-ANT analyzer cannot be mounted on these sliders. Use the IX2-AN analyzer with them.

In case of simultaneous observation with reflected fluorescence observation, the use of the IX2-AN can make the observation brighter because it does not cause drop in the excitation light from the principles.

}It is also possible to use the IX2-MDICT DIC mirror unit in place of the analyzer.

However, the U-MDICT3 that looks similar to the IX2-MDICT cannot be used because the analyzer’s oscillation direction is different.

1. Hold the IX2-AN analyzer 5 so that the side with indication faces up, and insert the analyzer into the analyzer insertion slot 6 until it clicks.

2. Hold the DIC slider so that the side with indication faces down, and insert it in the same way as the U-DICT.

Fig. 48

Attaching the Polarizer (IX-LWPO)

(Fig. 48)

# The polarizer can be mounted only on the IX2-LWUCDA2 or IX2-LWUCD.

}This polarizer has been designed for being mounted on a universal condenser in case of DIC observation or simplified polarizer light observation.

1. Loosen the polarizer clamping screw 1 using the Allen screwdriver.

2. Align the pin hole on the condenser with the positioning pin 2 on the condenser, and insert the polarizer unit into the upper part of the condenser.

3. Tighten the polarizer clamping screw firmly.

Fig. 49

Cross-Nicol Adjustment

(Figs. 49 to 51)

1. Rotate the condenser’s turret for the BF (brightfield) light path (with no optical element engaged in the light path).

2. Move the polarizer detaching lever 1 on the IX-LWPO polarizer to engage the polarizer in the light path. (Fig. 49)

3. Engage the 10X objective in the light path, place an optimum specimen for brightfield observation on the stage, bring the specimen into approximate and remove the specimen out of the light path.

4. When the U-BI90CT, binocular observation tube is used, rotate the CT turret 2 to position “CT” to engage the CT lens in the light path. (Fig. 50)

When the U-BI90/U-TBI90 binocular observation tube or U-TR30H-2 trinocular observation tube is used, remove an eyepiece and attach the U-CT30 centering telescope.

5. Rotate the focusing ring 3 (or, with the centering telescope, rotate the knurled section) to bring the objective’s exit pupil into focus. (Fig. 50)

6. Move the prism movement knob 7 of the DIC slider in the clockwise direction around the axis until, the knob is stopped. A black interference stripe then a rainbow-colored interference stripe will be observed. Here, stop the knob at the position with which the black interference stripe can be seen. (Figs. 46 & 51)

7. While observing the objective’s exit pupil, rotate the polarizer rotation/ clamping knob 4 on the polarizer unit horizontally until the black interference stripe becomes darkest. This is the position for use of the polarizer.

(Figs. 49 & 51)

8. After determining the position, clamp the polarizer rotation/clamping knob so that the polarizer will not rotate.

Fig. 51

IX81

Observation Method

1. Rotate the condenser turret to engage the suitable optical element for the objective in use in the light path.

2. Engage the objective to be used in the light path.

3. Place the specimen on the stage and bring the specimen into focus by moving the objective up or down.

4. Adjust the field iris diaphragm so that its image circumscribes the field of view.

5. Adjust the aperture iris diaphragm to enhance the contrast.

6. Move the prism movement knob of the DIC slider to select the interference color that can provide the optimum contrast in accordance with the specimen.

U-DICT: The background interference color is continuously variable from the gray sensitive color to purple sensitive color.

U-DICTS:

U-DICTHC:

The background interference color is continuously variable from black to light gray.

U-DICTHR:

}With sensitive color observation using the U-UCD8, engage the U-

UCDTP530 1 plate (sensitive color plate) in the light path.

· Setting the background color to dark enables an observation like darkfield observation.

· Setting the background color to gray provides observation with high contrast and 3D feeling with the gray sensitive color with which the sensitivity is highest.

· Setting the background color to gray allows very small change in phase to be observed as a change in color.

· There is a directional characteristic with the detection sensitivity because of the configuration of the DIC prism. As a result, the contrast may sometimes be improved by rotating the specimen on the stage.

# For simultaneous observation with reflected fluorescence observation, refer to the instruction manual entitled “Manual/Motorized Reflected Fluorescence System”.

5-3 Simplified Polarized Light Observation

}An analyzer and polarizer are required for simplified polarized light observation. The applicable condenser is the

IX2-LWUCDA2 or IX2-LWUCD. Simplified polarized light observation is not available with the IX-ULWCD.

Attaching the Analyzer and Polarizer

}Use the same procedure as that for attaching the analyzer and polarizer for DIC observation (see page 34).

PHOTOMICROGRAPHY AND TV OBSERVATION

IX81

6-1 Photomicrography

}Use the U-TR30H-2 trinocular observation tube or the side port for photomicrography.

Photomicrography can be performed using the PM-10, PM-20 or PM-30 photomicrographic system.

For how to use the photomicrographic system, see the instruction manual of the photomicrographic system in use. The following are procedures related to this microscope.

Fig. 53

Attaching the Straight Photo Tube

(IX2-SPT/IX-SPT)

(Figs. 53 & 54)

When the U-TR30H-2 trinocular observation tube is used

(in combination with the IX-SPT)

(Fig. 53)

# The U-SPT straight photo tube cannot be mounted.

1. Using the Allen screwdriver, loosen the clamping screw 1 on the photo port of the trinocular observation tube and remove the cap.

2. Align index 2 on the front pf the photo port of the trinocular observation tube with index 3 on the IX-SPT straight photo tube, then fit the circular dovetail of the straight photo tube into the photo port of the trinocular observation tube.

3. Tighten the clamping screw 1 firmly.

When the side port is used (in combination with the IX2-SPT) (Fig. 54)

1. Using the Allen screwdriver, loosen the side port clamping screw 1 of the microscope frame.

2. Align index 2 on the IX2-SPT straight photo tube with positioning index

3 on the side port and fit the straight photo tube.

3. Tighten the clamping screw 1 firmly.

Fig. 54

Attaching the Photo Eyepiece

(Fig. 55)

Use only a PE photo eyepiece for photomicrography.

Insert the PE photo eyepiece 1 into the photographic system mount on the straight photo tube.

}The IX2-SPT or IX-SPT is equipped with a plunger for use in preventing movement of the PE photo eyepiece. Be sure to push in the plunger.

Fig. 55

Fig. 56

Fig. 57

Fig. 58

Attaching the Photomicrographic system

(Fig. 56)

· Attach the photomicrographic system directly onto the photomicrographic system mount on the straight photo tube.

Align indices 1 on the straight photo tube and photomicrographic system and clamp.

The photomicrographic system can also be mounted on the side port in the same way as above.

Switching to the Photomicrography Light Path

See the description in “Observation Tube” on page 19.

Adjusting the Focus

(Figs. 57 & 58)

}Focus adjustment for photomicrography is performed by attaching optimum finder eyepieces for each film size onto the binocular section of a trinocular observation tube or through the viewfinder of the photomicrographic system.

If the photomicrographic system is attached on the side port, focusing is impossible because the parfocality with the finder eyepieces is not adjusted. In this case, adjust focusing directly through the viewfinder of the photomicrographic system. If the viewfinder is hard to view, it is recommended to use the optional U-FTV V-shaped focusing telescope @.

# Note that finder eyepieces cannot be attached to the U-BI90CT and

U-BI90 binocular observation tubes.

}The finder eyepieces show four photo masks. The numbers given to the masks correspond to the magnifications of the photo eyepiece. (Fig. 57)

1. Adjust the diopter of the eyepieces and focus on the photo masks in advance. Focus so that the double crosslines are sharply visible as two distinct lines. (Fig. 57)

2. Bring the specimen into focus using the focus adjustment knob. As the reticles of photo masks and the film plane are optically in precise alignment, adjust focusing so that both the double crosslines and specimen are sharply visible.

}Because of the great depths of focus of 4X objectives, use an optional

U-FT focusing telescope for accurate focusing using these low-power objectives.

}If the viewfinder of the photomicrographic system mounted on the side port is hard to view, it is recommended to use the optional U-FTV V-shaped focusing telescope. (Fig. 58)

Using the U-FTV

· Rotate the diopter correction ring of the viewfinder to the +2 index position.

· Slide the top portion of the U-FTV 1 up or down until the photo masks are brought into focus. (Fig. 58)

<<

Photographic Magnification

>>

· 35 mm photo magnification = Objective magnification x PE photo eyepiece x Magnification change value

· Large format camera back magnification = 35 mm photo magnification x 3

IX81

Adjusting the Illumination

Correct illumination is more crucial for photomicrography than for observation because flawless pictures cannot be obtained unless the illuminating light is properly adjusted. To avoid uneven illumination, especially with high contrast films, adjust the illuminating light by carefully following the observation procedure.

Influence of Radial Heat of Illumination

Even at optimum illumination setting for observation and photomicrography, the illuminating light will generate considerable radiant heat, which may damage living specimens.

In case of DIC observation, special caution should be exercised in the following points.

· Reduce light intensity for observation as low as possible.

· Use additional heat barrier filters for observation.

· For time-lapse photography, synchronize the on/off of the light bulb with the exposure.

Setting the Filter and Lamp Intensity

Set the lamp intensity and filters in accordance with the film to be used.

Film Filter Light Intensity Control Button

Daylight color film 45LBD-IF

Tungsten type color film 45LBT

B&W film

Camera symbol position

43IF550-W45 Other position than camera symbol position

# To match your preference in color rendition, make test exposures for determining the lamp intensity.

}When the IF550 filter is not used for color photography of phase contrast images, a neutral color is obtained by combining

LBD filters and setting the lamp light intensity at around the lower limit of the camera symbol.

6-2 TV Observation

}The following four methods are available for TV observation.

1. Attaching the video camera onto the side port

2. Attaching the video camera to the U-TR30H-2 trinocular observation tube H

3. Attaching the video camera onto the IX2-LBPC C-mount unit for lower back port (To be installed by the manufacturer)

4. Attaching the video camera onto the IX2-TVR/IX2-TVRAC bottom TV port unit (To be installed by the manufacturer)

Attaching the Camera on the Side Port

}The side port provides primary observation images that are brighter and higher in resolution than those obtained with the trinocular observation tube H.

· Compatibility with various mounts from different manufacturers can be obtained by using the IX2-SPT straight photo tube

+ TV system for the BX series or by using a TV adapter for the BX series. However, this does not apply to the U-TVCAC and

U-DPT.

· For the installation of the IX2-SPT, see page 38.

9-2 Detailed Assembly Procedures

# Be always sure to use the U-ZPCB(T2) Z-board.

The following phenomena will occur if the U-ZPCB is used, even though the correct setup is performed:

· The rotation direction of the focusing knob is opposite to the actual movement direction of the objectives.

· Initialization may not be possible depending on the position of the focusing block. (The microscope may not start up.)

S1 S2

Setting Up and Mounting the Z-Board

}The on-board DIP switches on the Z-board have been designed for use with the BX61 or BX62 microscope at the factory (i.e. all of the S1, S2 and

S3 switches at the OFF positions).

Change the setup of the DIP switches to enable the use of the Z-board with the IX81.

Changing the On-Board DIP Switch Setting (Fig. 60)

# Set all other switches than those listed below to the OFF positions.

· S3 Set No. 4 and No. 5 to ON.

# If the setting is not correct, the objective may raise and hit the specimen during initialization.

Attaching the Stage

(Figs. 66 to 68)

}The following stage mounting procedures are commonly applicable to the IX2-SFR, IX-SVL2 and IX2-SP.

}When mounting the IX-MVR mechanical stage, first attach it the IX2-SP plain stage in advance (see the description on the bottom of this page).

1. Gently place the stage on the microscope frame by aligning the stage mounting holes with the threaded holes on the frame.

2. Insert the four provided Allen screws into the mounting holes 1. Tighten the screws using the provided Allen wrench. (Fig. 66)

3. Fit the stage center plate 2 into the stage. (Fig. 67)

# The stage center plate is designed very thin so that the objective will not hit it when the revolving nosepiece is rotated. Do not subject the stage center plate to impact or excessive force, as this may deform it.

}To facilitate confirmation of the objective front lens position and application of oil for oil immersion objectives, rotate the stage center plate so that the keyhole 3 will be facing the front. (Fig. 67)

Fig. 67

4. Screw the IX-SCL stage clips 4 into the threaded holes provided on the stage top surface. (Fig. 68)

}The IX2-SFR stage can be mounted by reversing the front and rear to implement a stage with knobs on the right position. In this case, however, the left focusing knob comes in the way of the stage operation so it may be necessary to remove the left focusing knob by removing the clamping screw using the Allen screwdriver. The positioning bracket provided with the stage should not be attached in this case.

Fig. 68

Fig. 69

Mechanical Stage (IX-MVR) (Figs. 69 to 71)

<< Attaching Procedure >>

1. Invert the mechanical stage 1 upside down. Also invert the IX2-SP plain stage 2 and place it on top of the inverted mechanical stage. (Fig. 69)

2. Align the two mounting holes 3 on the mechanical stage with the mounting holes 4 on the plain stage. Insert the two clamping screws 5 and tighten using the Allen screwdriver.

# The mechanical stage may also be attached to the left side of the plain stage. However, this will interfere with the operation of the stage travel knobs, focusing knobs and the revolving nosepiece. To avoid this, always attach the mechanical stage on the right side of the plain stage.
