IMPORTANT

This microscope employs a UIS (Universal Infinity System) optical design, and should be used only with

UIS eyepieces, objectives and condensers for the BX2 series. (Some of the modules designed for the BX series are also usable. For details, please consult Olympus or the catalogue.) Less than optimum performance may result if inappropriate accessories are used.

SAFETY PRECAUTIONS

Fig. 1

Fig. 2

(Fig. 1)

1. Install the microscope on a sturdy, level table or bench so as not to block the air vents on the underside of the base.

Do not place the microscope on a flexible surface, as this could result in blocking the air vents and cause overheating or a fire.

2. To prevent obstruction of the natural convection-based air cooling of the microscope, make sure to leave at least 10 cm of free space between walls or other objects, and the left, right and rear sides of the microscope and the lamp socket when installing the microscope.

3. To avoid potential shock hazards and burns when replacing the light bulb, set the main switch @ to “ ” (OFF) then disconnect the power cord from the wall outlet in advance. Whenever you replace the bulb during use or right after use, allow the lamp socket ² and bulb to cool before touching. (Figs. 1 & 2)

Designated bulb 6V30WHAL (PHILIPS 5761)

# The microscope also incorporate a fuse (this should be replaced by the manufacturer or authorized agent).

4. Make sure the voltage selector switch ³ located on the rear side of the microscope frame is set to conform with the local supply voltage. (When shipped from the factory, the switch is set to 220-240 V.)

5. Always use the power cord provided by Olympus. If no power cord is provided, please select the proper power cord by referring to the section

“PROPER SELECTION OF THE POWER SUPPLY CORD” at the end of this instruction manual. If the proper power cord is not used, product safety and performance cannot be guaranteed.

6. Always ensure that the grounding terminal of the microscope and that of the wall outlet are properly connected. If the equipment is not grounded,

Olympus can no longer warrant the electrical safety and performance of the equipment.

7. Never insert metallic objects into the air vents of the microscope frame as this could result in electrical shock, personal injury and equipment damage.

8. The power cord may be melt by the heat of lamp socket if the cord comes in contact with it. Distribute the power cord at an enough distance from the lamp socket.

Getting Ready

Fig. 3

1. A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impact.

2. Do not use the microscope where it is subjected to direct sunlight, high temperature and humidity, dust or vibrations. (For the operating conditions, refer to section 5, “SPECIFICATIONS”.)

3. When moving the microscope, carefully carry it with the grasping part on the rear of the arm and the base as shown in Fig. 3 (Weight: approx. 13 kg).

# If an intermediate attachment hinders you grasp the grasping part on the rear, remove the intermediate attachment before carrying.

# Damage to the microscope will occur if you grasp it by the stage, coarse/fine adjustment knob or binocular section of the observation tube.

4. The BX41 can be used with up to two intermediate attachments (e.g. a U-

CA magnification changer, U-EPA2 eyepoint adjuster, etc.). For restrictions when using two intermediate attachments, make sure to read the instruction manual provided with the respective intermediate attachments.

# Be careful in attaching the U-TRU trinocular attachment horizontally, for this makes the entire microscope unstable.

Maintenance and Storage

1. Clean all glass components by wiping gently with gauze. To remove fingerprints or oil smudges, wipe with gauze slightly moistened with a mixture of ether (70%) and alcohol (30%).

Since solvents such as ether and alcohol are highly flammable, they must be handled carefully. Be sure to keep these chemicals away from open flames or potential sources of electrical sparks –– for example, electrical equipment that is being switched on or off. Also remember to always use these chemicals only in a well-ventilated room.

2. The filter mount lens on the base is made of plastic. Do not rub it with a strong force to prevent damaging it.

3. Do not attempt to use organic solvents to clean the microscope components other than the glass components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted neutral detergent.

4. Do not disassemble any part of the microscope as this could result in malfunction or reduced performance.

5. When not using the microscope, keep it covered with a dust cover.

2. The numerals ² below the knob indicate the approximate voltage.

Fig. 4

Fig. 5

Using the Light Intensity Preset Switch

(Fig. 5)

}The light intensity preset switch @ makes it possible to limit the light intensity to a preselected level regardless of the position of the brightness adjustment knob. The light intensity preset switch has been set to about 4 V at the factory.

1. Press the light intensity preset switch @ to the ON position. (The face of the switch lights when it is ON.)

2. Using a small flat-blade screwdriver, turn the preset adjustment screw ² to obtain the required light intensity. Turning the screw clockwise increases brightness.

3. When the light intensity preset switch is set to OFF, the brightness returns to the level set by the brightness adjustment knob.

}While the light intensity preset switch is ON, turning the brightness adjustment knob does not affect brightness.

Using the Filters

(Figs. 6 - 10)

}You can place a filter in the light path with either method.

· Place a filter on the filter mount on the base and engage in the light path.

(Page 7)

· Insert a filter in the U-FC filter cassette, attach it on the filter mount and engage it in the light path by sliding the filter level. (Page 8)

Mounting a Single Filter (Fig. 6)

A filter with a diameter of 45 mm can be placed on the filter mount on the base. If you need to place multiple filters, please purchase the U-FC filter cassette.

# Even when a filter cassette is used, a filter with thickness of no more than 3 mm can still be placed on the filter mount.

Using the Filter Cassette (Figs. 7 - 10)

Loading Filters into Filter Cassette

}The filter cassette accommodates filters with a diameter of 45 mm and thickness of 2.7 mm or less.

}The filter cassette has two filter levels on the right side and one on the left side.

1. Move all filter levers to the OUT position except for the one belonging to the slot into which the filter is to be inserted.

2. Slide lever @ to the IN position. Make sure that it clicks securely into place. (Fig. 7)

3. Holding the lever in the position shown in Fig. 7, put the filter into the cassette by inserting it in the direction indicated by the arrow.

4. Insert the other two filters in the same manner.

Mounting the Filter Cassette

1. Fully loosen the filter cassette clamping screw ². (Fig. 8)

2. Align the key ³ on the bottom surface of the filter cassette with the positioning slot | on the filter mount, then snap the filter cassette into place from above.

3. Rotate the filter cassette to align its sides with the base. (Fig. 9)

4. Align the clamping screw ² with the positioning hole ƒ on the filter mount, then tighten the screw to fasten the filter cassette.

# When the filter cassette is installed, the condenser may hit it when the stage is lowered. Therefore, exercise caution when lowering the stage with the filter cassette installed.

Replacing the Fine Adjustment Knob

(Fig. 11)

# The fine adjustment knob has been attached on the right side at the factory.

}The fine adjustment knob is designed detachable to prevent interference with hand during manipulation of the X-and Y-axis knobs.

Usually attach the knob on the opposite side to the X- and Y-axis knobs.

1. Using the Allen screwdriver, loosen the clamping screw @ and remove the fine adjustment knob ².

2. Remove the seal from the fine adjustment knob screw hole on the other side and attach the knob by reversing the removal procedure.

3. Attach a provided seal on the screw hole | of the removed fine adjustment knob.

}The fine adjustment dial ³ can be operated with your fingertip or finger surface at the same time as manipulating the X- and Y-axis knobs.

Adjusting the Coarse Adjustment Knob

Tension

(Fig. 12)

# Adjust the coarse adjustment knob tension using the tension adjustment ring.

The coarse adjustment knob tension is preadjusted for easy use. However, if desired, you can change the tension using the tension adjustment ring @. Turning the ring in the direction of the arrow increases tension, and vice versa.

The tension is too low if the stage drops by itself of focus is quickly lost after adjustment with the fine adjustment knob. In this case, turn the ring in the direction of the arrow to increase tension.

Pre-focusing Lever

(Fig. 13)

}The pre-focusing lever ensures that the objective does not come in contact with the specimen and simplifies focusing.

After focusing on the specimen with the coarse adjustment knob, turn this lever @ in the direction of the arrow and lock; the upper limit on coarse adjustment movement is set at the locked position.

After changing a specimen, refocusing is easily accomplished by rotating the coarse adjustment knob to reach the pre-focused position, then making fine adjustments with the fine adjustment knob.

}Stage movement with the fine adjustment knob is not locked.

# When the pre-focusing lever is locked, a coarse movement stroke is reduced due to the microscope’s mechanism, causing the stage not to be able to be lowered to the lower limit. To lower the stage to the lower limit, release the pre-focusing lever.

BX41

3-3 Stage

Fig. 14

Placing the Specimen

# The dimensions of the slide glass should be 26 x 76 mm with thickness of 0.9 to 1.4 mm, and the cover glass should have thickness of

0.17 mm.

# When observing very large specimens, remove the slide holder and place the specimen directly on the stage.

Microscopy with Double-Slide Holder (Fig. 14)

1. Turn the coarse adjustment knob @ to lower the stage.

2. Open the spring-loaded curved finger ² on the slide holder and place one or two specimen slides on the stage from the front.

3. After placing the sides as far as they will go, gently release the curved finger.

Microscopy with Single-Slide Holder (Fig. 15)

The specimen side can easily be placed by sliding it into the slide holder from the front.

Fig. 15

Using an Oil Immersion Objective

Adsorption of immersion oil can cause the specimen to drift. In such cases, it is recommended to use the optional BH2-SCB-3 specimen clip

³ for oil immersion objectives. (Fig. 16)

Using an Oil Immersion Condenser

It may be effective to use the optional U-SVRO (right-hand knob) or U-

SVLO (left-hand knob) slotted stage which prevents close contact between the specimen and stage.

Fig. 16

Fig. 17

Adjusting the X- and Y-Axis Knob Tension

(Fig. 17)

1. Hold the X-axis knob @ and slide up the Y-axis knob ² up to expose the adjustment knobs.

2. Turning the X-axis adjustment knob ³ or Y-axis adjustment knob | clockwise (in the direction of the arrow) increases the tension and counterclockwise decreases it.

# If the tension is adjusted to tight, a creaking sound may be heard during stage travel, and the stage stopping accuracy may be imperiled.

CAUTION

After long hours of use, the stage guide may be deviated and the stage travel range may be decreased.

However, this is not malfunction and can be corrected easily as described below.

[Treatment]

Horizontal direction: Hold the specimen holder and move the stage guide to the left and right so that it hits the stoppers.

Vertical direction: Hold the upper stage and move it to the front and rear so that it hits the stoppers.

Stage Knob Rubbers (Optional)

}When the X- and Y-axis knobs are fitted with the rubber caps, the knobs can be adjusted without slipping and fine adjustment is possible by holding the knobs with a very light force. The rubber caps also reduce fatigue after long hours of operation.

The U-SHGT thick type (thickness 5 mm) and U-SHG thin type (thickness

2 mm) rubber caps are available.

To attach the rubber caps:

First fit the larger knob rubber to the Y-axis (upper) knob from below it, then fit the smaller knob rubber to the X-axis (lower) knob from below it.

3-5 Condenser

Fig. 29

Centering the Condenser

(Figs. 29 & 30)

1. Turn the condenser height adjustment knob @ to raise the condenser to its upper limit.

2. Focus on the specimen using the 10X objective.

# When using the U-SC3 swing-out condenser, move the top lens into the light path.

3. Rotate the field iris diaphragm ring ² in the direction of the arrow so that the diaphragm image comes inside the field of view.

4. Manipulate the condenser height adjustment knob @ to focus on the diaphragm image

5. Turn the two condenser centering screws ³ to move the iris diaphragm image to the center of the field of view.

6. Gradually open the field iris diaphragm. The condenser is properly centered if the iris image is centered and inscribed in the field of view.

7. During actual use, open the field diaphragm slightly until its image circumscribes the field of view.

Fig. 30

Effects of Field Iris Diaphragm (Fig. 30)

The field iris diaphragm restricts the diameter of the beam of light entering the objective and thus excludes extraneous light, improving image contrast. The diameter of the field iris should e adjusted for objective power to the extent that it just circumscribes the field of view. (See “Compatibility of Objectives and Condensers” on the next page.)

Aperture iris diaphragm image

Objective pupil

Fig. 31

70-80%

30-20%

Aperture Iris Diaphragm (Figs. 31 & 32)

The aperture iris diaphragm determines the numerical aperture of the illumination system. Matching the numerical aperture of the illumination system with that of the objective provides better image resolution and contrast, and also increases the depth of focus.

Since the contrast of microscope specimens is ordinarily low, setting the condenser aperture iris diaphragm to between 70% and 80% of the N.A.

of the objective in use is usually recommended. If necessary, adjust the ratio by removing the eyepiece and looking into the eyepiece sleeve while adjusting the aperture iris diaphragm ring @ until the image shown in Fig. 31 is seen.

}Using the numerical aperture scale:

Set the condenser numerical aperture scale to about 80% of the NA value ² of the respective objective. (Fig. 32)

Example: With the UPlanFI40X (NA 0.75), set the scale to 0.75 x 0.8 = 0.6.

** When using the U-AC2 Abbe condenser, the field iris diaphragm image cannot be viewed with a 100X objective.

}To obtain better illumination in photomicrography using a 1.25X to 4X objective, use of the U-ULC-2 is recommended.

BX41

3-6 Immersion Objectives

# Be sure to use the provided Olympus Immersion oil.

Fig. 33

Using Immersion Objectives

(Fig. 33)

1. Focus on the specimen with objectives in the order of lower-power to higher-power ones.

2. Before engaging the immersion objective, place a drop of provided immersion oil onto the specimen at the area to be observed.

3. Turn the revolving nosepiece to engage the immersion objective, then focus using the fine adjustment knob.

# Since air bubbles in the oil will affect the image quality, make sure that the oil is free of bubbles.

a. To check for bubbles, remove the eyepiece and fully open the field and aperture iris diaphragms, then look at the exit pupil of the objective inside the observation tube. (The pupil should appear round and bright.) b. To remove bubbles, turn the revolving nosepiece to repeatedly defocus and refocus the oil immersion objective.

}If the condenser engraving shows a numerical aperture (NA) of 1.0 or higher, the number applies only when oil is applied between the slide glass and the top surface of the condenser. When oil is not present, the

NA is about 0.9.

4. After use, remove oil from the objective front lens by wiping with gauze slightly moistened with an ether (70%)/alcohol (30%) mixture.

Caution in use of immersion oil

If immersion oil enters your eyes or contacts with your skin, immediately take the following treatment.

Eyes: Rinse with fresh water (for 15 minutes or more).

Skin: Rinse with water and soap.

If the appearance of the eyes or skin is altered or pain persists, immediately see your doctor.

3-7 Objectives with Correction Collar

Fig. 34

}If the cover glass thickness is not 0.17 mm, the objectives cannot manifest their performances. If a correction collar equipped objective is used in this case, the difference in thickness can be compensated for by adjusting the collar.

Adjustment Procedure

· If the cover glass thickness is known, set the correction collar @ to that value. (Fig. 34)

· If the cover glass thickness is unknown, adjust the correction collar @ and fine adjustment knob alternately until the positioning with the highest resolution is obtained.

# Be careful not to touch the correction collar @ when turning the revolving nosepiece.

7-2 Detailed Assembly Procedures

Installing the Bulb and Lamp Socket

(Figs. 35 & 36)

Use only the designated bulb 6V30WHAL (PHILIPS 5761).

1. Holding the bulb @ with gloves or a piece of gauze, insert the bulb pins

² straight and fully into the pin holes ³ on the lamp socket.

# To prevent reduced bulb life or cracking, do not touch the bulb with bare hands. If fingerprints are accidentally left on the bulb, wipe the bulb with a soft cloth.

Fig. 35

† …

Fig. 36

2. Aligning the guide pins | with the guide pin holes ƒ at the rear of the microscope frame, and the plug … with the socket †, gently push the lamp socket all the way into place.

Caution for Bulb Replacement During Use or Right After Use

The bulb and the lamp socket are areas near these will be extremely hot during and right after use.

Set the main switch to “ ” (OFF), disconnect the power cord from the wall outlet, then allow the old bulb and lamp socket to cool before replacing the bulb with a new of the designated type.

Fig. 37

Attaching the Condenser

(Fig. 37)

1. Turn the coarse adjustment knob @ to raise the stage to its upper limit.

2. Turn the condenser height adjustment knob ² to lower the condenser holder to its lowest position.

3. Fully loosen the condenser clamping knob ³.

4. Position the condenser so that the aperture scale is located in front.

Gently slide the condenser along the dovetail all the way until it is stopped.

}When attaching the U-SC3 swing-out condenser, align the positioning pin at the back of the condenser with the groove in the condenser sleeve.

# When attaching a condenser with swing-out top lens, swing out the top lens out of the way before inserting the condenser.

5. Tighten the condenser clamping knob and gently raise the condenser holder to its highest position.

Attaching the Eyepiece

(Fig. 38)

# When using the U-BI30-2 binocular tube, eyepieces with built-in micrometer disk cannot be attached.

# When using a finder eyepiece or an eyepiece with focusing mirror, attach it to the right-hand eyepiece sleeve.

When doing so, make sure that the eyepiece positioning pin @ fits into the notch ² on the eyepiece sleeve.

}The super-widefield trinocular observation tube is equipped with a positioning notch on both eyepiece sleeves. Make sure that the positioning pins on both eyepieces fits into the respective notches.

Attaching the Power Cord

(Figs. 39 & 40)

The power cord is vulnerable when bent or twisted. Never subject it to excessive force.

Make sure that the main switch @ is set to “ ” (OFF) before connecting the power cord.

Always use the power cord provided by Olympus. IF no power cord is provided with the microscope, please select the proper power cord by referring to section “PROPER SELECTION OF THE POWER

SUPPLY CORD” at the end of this instruction manual.

1. Connect the power cord plug ² to the AC receptacle ³.

The power cord should be connected to a grounded, 3-conductor power outlet. If the power outlet is not grounded properly, Olympus can no longer warrant the electrical safety performance of the equipment.

2. Plug the power cord plug | into the wall outlet ƒ.

If the power cord comes in contact with the lamp socket or the surroundings, the cord may melt down, causing electric shock hazards. Be sure to distribute the power cord at enough distance from the lamp socket.
