Turn it clockwise. The degree increases.
Turn it counterclockwise. The degree decreases.
Even if the diopter is adjusted, the tube length
remains correct. So the performance of the objective
is exerted fully and the focus becomes clearer when
the objective is replaced.

Procedure of adjusting the diopter of both eyes
This microscope enables observation through the binocular part using both eyes. By adjusting the diopter
for the right and left eye separately with the following procedure, the difference between the right and left
eyes are corrected so that observation with both eyes is performed easily.
1. In the BF microscopy status, focus the 10x objective on the specimen.
2. Turn the diopter correction collar of the eyepiece for each eye to align the ruling line of the
diopter correction collar with the rim of the outer ring of the eyepiece.
This position is used as the position of diopter correction “0.”
3. Place the 40x objective into the optical path.
4. While looking through the left eyepiece with your left eye, focus on the specimen by turning the
focus knobs.
5. Place the 4x or 10x objective into the optical path.
6. While looking through the left eyepiece with your left eye, focus on the specimen by turning the
diopter correction collar of the left eyepiece.
Do not touch the focus knobs of the microscope.
7. Repeat steps 3 to 6 above twice.
8. Adjust the right eyepiece in the same way.
Perform steps 3 to 7 for the right eyepiece.
