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).
7. Look through the left eyepiece only.
8. Turn the eyepiece slowly in the "–" direc-
tion until the specimen appears sharp.
Parfocality
Like all other Leica stereomicroscopes,
the Leica A60 F is parfocally matched.
The prerequisite for this is the correct setting of
the diopters for the respective user. The follow-
ing adjustments have to be carried out only
once by each user.
Adjusting
1. Set the dioptric correction for both
eyepieces to "0".
2. Select the lowest magnification and focus
on a flat specimen.
9. Look through the right eyepiece and repeat
item 8.
10. Select the highest magnification and refo-
cus if necessary.
Now, if you adjust the magnification from the
highest to the lowest level, the specimen is
always brought into sharp focus. If not, repeat
the process. The microscope is now parfocally
matched to your eyes.
11. Write down your values and configure
them BEFORE each time you begin work.
Check the diopter settings at regular
intervals.
