Adjusting

1. Set the dioptric correction for both

eyepieces to "0".

2. Select the lowest magniﬁcation and focus

on a ﬂat specimen.

3. Select the highest magniﬁcation and read-

just the sharpness.

4. Select the lowest magniﬁcation again, but

do not look into the eyepieces.

6. Rotate the eyepieces counterclockwise in

the "+" direction as far as they will go (+5

diopter settings).

Leica stereomicroscopes are parfocally matched.

The prerequisite for this is the correct setting of

the diopters and the parfocality. The following

adjustments only have to be carried out once

by each user.

Preparations

Move the lever of the video/phototube to ★

the "observation" position and open the

diaphragm.

If you are using the microscope carrier AX, ★

set it to stereoscopic observation.

7. Look into the eyepieces.

8. Slowly rotate each eyepiece individually

in the "–" direction until each eye sees the

object sharply imaged.

9. Select the highest magniﬁcation and refo-

cus if necessary.

Now, if you adjust the magniﬁcation from the

lowest to the highest level, the specimen is

always brought into sharp focus. If not, repeat

the process.
