Using Oil- or Water-Immersion Objective

} If you use an oil-immersion objective, use immersion oil as described

below.

Always use immersion oil supplied by Olympus.

CAUTION

} 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

CAUTION

oil-proof 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

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.
