Adjusting the aperture diaphragm (AS)

Using the eye shades

When wearing eyeglasses

Use the eye shades in the normal, folded-down position.

When not wearing eyeglasses

Extend the folded eye shades in the arrow direction. Since the eye

shades prevent the unnecessary light from entering between eyepieces

and eyes, you can observe the specimen comfortably.

The aperture diaphragm is a diaphragm to adjust the numerical aperture

of the condenser.

Adjusting the numerical aperture of the condenser appropriately

with respect to the numerical aperture of each objective allows

you to observe the specimen with the best contrast and resolution.

(For the aperture diaphragm, see page 22.)

NOTE

For darkfield observation, the darkfield ring slit CH2-DS (option) and the filter

holder CH2-FH (option) must be attached to the condenser.

NOTE

Move the aperture diaphragm lever a to right and left direction to

match the index with the magnification of the objective in use.

For darkfield observation, open the aperture diaphragm.

Insert the darkfield ring CH2-DS a into the filter holder CH2-FH b .

Push the filter holder b which includes the darkfield ring into the bottom

of the condenser c until the click sound is heard.

The darkfield observation is not available with the 100X oil

immersion objective.
