8.1.2 Adjusting the diopter
This operation corrects the difference
between the left and right visions of the
observer.
1. Set the scales of diopter adjustment rings [a]
of right and left sides to "0".
2. Engage a low magnification objective (e.g.
10X) in the light path and rotate coarse/fine
focusing knobs to bring the specimen into
focus.
3. Change to the high magnification objective (e.g. 20X) and rotate coarse/ fine focusing knobs to
bring the specimen into focus.
4. Change to the low magnification objective (e.g. 10X). While looking into the right eyepiece with
your right eye, rotate the right diopter adjustment ring [a] to bring the specimen into focus. In the
same manner, while looking into the left eyepiece with your left eye, rotate the left diopter
adjustment ring [b] to bring the specimen into focus.
In this case, do not touch the coarse/fine focusing knobs.
5. Change to the high magnification objective (e.g. 20X) and rotate coarse/ fine focusing knobs to
bring the specimen into focus.
6. Change to the low magnification objective (e.g. 10X) and confirm that the specimen is brought
into focus with the right and left eyepieces.
7. If the specimen is not brought into focus, repeat steps from [4] to [6] to adjust again.
8.1.3 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. The observation becomes
comfortable since it prevents unnecessary
light from entering between the eyepieces and eyes.
