Objectives - Leica MacroFluo User Manual

2.7 Objectives

– We recommend using the 1×, 2×, 0.8×, 0.5×
planapochromatic objectives, in order to take
advantage of the high performance of the
apochromatic zoom system.
– Use the objectives directly on the diaphragm ring
of the zoom system or with fine focusing.
Remove the diaphragm ring if the fine focusing is
used (see below).
– A planapochromatic 5× HR objective is available
for magnifications in the microrange (see assem-
bly diagram p. 10). Always use the HR objective
with fine focusing.
– The Leica M series 0.63×, 0.5×, 0.32× achromatic
objectives, which can be attached to the
diaphragm ring of the zoom system or the fine
focusing using an adapter (see assembly dia-
gram on p. 10), can also be used.
Diaphragm ring
At the bottom of the zoom system is a diaphragm
ring (4.4). The diaphragm ring must be removed if
fine focusing is used.
