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
