Getting Started

Fig. 2

1. A microscope is a precision instrument with delicate glass components.

Please handle with care.

2. Do not use the microscope where it is subjected to direct sunlight, high temperature , humidity, dust and vibrations. (For the operating conditions, see chapter 14, "SPECIFICATIONS")

3. The microscope is ventilated by natural convection. Be sure to leave enough space (10 cm or more) around body when installing the unit.

4. Arm handle is provided for carrying the microscope.

!

To prevent damage, do not hold the microscope by the stage or observation tube.

Be sure to remove the specimen from the stage clip while transporting unit to avoid damage to the specimen slide.

2

Maintenance and Storage

1. Clean all glass components by wiping gently with cleaning cloth provided. To remove fingerprints or oil smudges,

!

wipe with cleaning cloth slightly moistened with a mixture of petroleum (85%) and isopropanol (15%).

Since solvents such as petroleum and isopropanol 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 and ventilated room.

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

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

4. When not using the microscope, ensure that the frame is fully cooled before storing the unit in a dry locker or covering with a dust cover

(provided).

5. To clean the condenser, fully loosen the securing knobs and remove the condenser by lowering condenser bracket then, wipe the front lens of the condenser with optical cleaning solution (mixture suggested above) and lens tissue.

The condenser can be re-attached by replacing the condenser in its seat, tightening securing screws, and raising condenser bracket to desired position.

Care & Maintenance

Your microscope has been engineered for a long and safe operational life with the least amount of maintenance required. In general, routine maintenance is limited to keeping the microscopes working parts lubricated and optics clean. Always cover the microscope with the provided dust cover when not in use.

Optical Cleaning:

1. The objectives have been adjusted for a tight fit to prevent any damage during transportation. To remove an objective, rotate it counterclockwise while gripping it with a rubber sheet, etc. to avoid any slippage.

2. To clean the lens surfaces, remove dust using a soft brush or compressed air (cans available at your local electronics store). For removing finger marks or grease, soft cleaning cloth or lens tissue lightly moistened with cleaning solution (85% petroleum ether and 15% isopropanol) should be used. For cleaning the objective optics, use Methanol. Observe sufficient caution in handling Methanol. Place the objectives and/or eyepieces on a dustfree surface (e.g. aluminum foil). All other optical components to be cleaned should be as accessible as possible.

3.. Blow all loose dust particles away with compressed air or mini dust blower.

4. Remove all water-soluble dirt with distilled water. If this is unsuccessful repeat using a solution of diluted hand soap liquid. Remove any remaining residue with a dry cotton swab.

5. To remove oil, use a solution of diluted hand-soap liquid initially. If this does not produce a satisfactory result, repeat the cleaning using a solvent (Optical Cleaning Solution 85% petroleum ether and 15% isopropanol).

6. Grease must always be removed using a solvent.

7. Cleaning is achieved by using a spiral motion from the center to the rim. Never wipe using zig-zag movements as this will only spread the dirt. With larger optical surfaces (e.g. tube lenses) the spiral motion starts initially at the rim before moving to the middle and is then followed by a center to rim cleaning motion. Normally several spiral wipes are recommended.

We recommend pure, volatile petroleum ether or Optical Cleaning Solution as explained in point 3 above.

zig-zag motion (X) spiral motion ( )

Wipe using a spiral movement. Do not use a zig-zag motion!

2.

Cleaning of painted surfaces :

Avoid the use of any organic solvent ( e.g. thinner, xylene, ether, alcohol etc.) for cleaning of painted surfaces of the instrument. Painted surfaces can be cleaned with a very lightly moistened micro fiber cloth. Loose dust and other dirt particles can be removed using a soft bristle brush used exclusively for this purpose.

Slide glass

Fig. 15

Cover glass

Cover glass

This is the glass plate placed on the specimen. For optimum optical performance, the cover glass thickness, which is the distance from its surface to the specimen surface, should be 0.17 mm.

Slide glass

This glass plate should ideally have a length of 76 mm, width of 26 mm

±1 mm and thickness between 0.9 and 1.4 mm.

“Vernier Scales”

These scales allow for easy identification of the specimen’s position

(coordinates), making it easy to return to a particular region of interest after scanning the slide. (Figure 16.)

1. The horizontal coordinate can be read at position (1) on the specimen

holder.

2. The vertical coordinate can be read at the index line (2).

Adjusting the Interpupillary Distance (IPD)

Fig. 18

The inter-pupillary distance adjustment consists of moving the two eyepieces to align with both eyes’ pupils so that you can observe a single microscopic image through two eyepieces in stereo vision. This greatly helps to reduce fatigue and discomfort during observation.

While looking through the eyepieces, move both eyepieces laterally until the left and right fields of view coincide completely. The position of index dot (•) indicates the inter-pupiliary distance value.

Note your interpupillary distance so that it can be quickly referred to in the future. This may need when multiple users work with the microscope.

5

Adjusting the Diopter

Procedure for adjusting the diopter:

1. Rotate the right eyepiece to match the markings of your IPD (If your

IPD is 64, rotate the eyepiece to 64 mark).

2. While looking through the right eyepiece with your right eye, rotate

the coarse and fine adjustment knobs to bring the specimen into

focus.

3. While looking through the left eyepiece with your left eye, rotate only

diopter adjustment ring on the eyepiece until specimen is at its best

possible focus.

Fig. 19

Using the Eye Guards

When Wearing Eyeglasses

Use with the eye guards in the normal, folded-down position. This will prevent the eyeglasses from being scratched.

When Not Wearing Eyeglasses

Extend the folded eye guards outwards (direction of the arrow) to prevent ambient light from entering into your line of vision.

Centering the Condenser

Fig. 21

There is a possibility of having the condenser de-centered during shipping. it is mandatory to check the centering before observing the specimen as it is required to distribute even light to the specimen.

For models with Koehler illumination:

1. Bring the 10x objective (1) in the front position.

2. Move the condenser to the highest point.

3. Close the koehler. (2) Focus the light spot as show in the illustration below.

4. Use the centering screws (3) provided on left and right sides of the condenser bracket to bring the light spot to center of the view field.

Using the 100X Immersion Objective

Fig. 24

The designated immersion oil should be in contact with the cover lens of the 100X immersion objective. If not, the specimen will appear distorted and dull. It is recommended that LABOMED immersion oil is always used.

Immersion Process:

1. Bring the specimen in focus using first the 10x, then 40x objective.

2. Disengage the 40x cycling towards 100x, and place a drop of immersion

oil on the center point of the specimen.

3. Rotate the revolving nosepiece to engage the immersion objective and

rotate the fine adjustment knob to bring the specimen into focus

(Since air bubbles in the oil will affect the image quality, make sure that the oil Is free of bubbles. To remove bubbles, rotate the revolving nosepiece slightly to agitate the oil).

4. The condenser of this microscope manifests the full performance when

oil is placed between the slide glass and the front lens of condenser. If oil

is not placed there, the observed image may appear dark.

5. After use, remove oil from the objective front lens by wiping with lens

tissue slightly moistened with an ether (70%) alcohol (30%) mixture.

Caution

If immersion oil makes contact with your eyes, rinse eyes out thoroughly with fresh water. If immersion oil makes contact with skin, wash affected areas with soap and water.

If prolonged discomfort is experienced, consult your physician immediately.
