Operation; Parfocality - Leica FluoCombi III User Manual

3. Operation

3.1 Setting the parfocality
If a 1× plan or planapo objective and a 5× or
20× HR objective is used, the focused position in
stereo and micro mode remains sharp (parfocal)
and centered (parcentric) with every zoom posi-
tion. For this reason, it is important to adjust the
parfocality precisely as described.
• We recommend performing the diopter setting
in transmitted or incident light. If the fluores-
cence illumination is activated, block the light
using the light stop and rotate the dummy filter
carrier into the beam path.
• Use a very fine, flat object that can still be
focused with precision at the highest magnifi-
cation.
• Zooming, focusing and adjusting interpupillary
distance, eyecups, diopter settings, working
distance, illumination see M2-105-0 or M2-160-4
(MZ16 FA) and M2-160-5 (MZ16 F) operating
instructions.
The following settings must be performed by every
user only once.
