Filter holder*/lamphousing
Filters with a diameter of 50 mm can be inserted
in the special filter holder (accessory, Fig. 9)
next to the lamphousing or in the microflash, or
placed on the microscope base (27.3) in
transmitted light.
Microscope base* and condenser*
Filters with a diameter of 32 mm and holders can
also be placed on the microscope base. The
mount on the underneath of the condenser
holder (27.6) should only be used for the
polarizer or whole- or quarter-wave compensa-
tors (57a,1 and 2).
Filters situated between the microscope base
and the condenser may cause disturbing
reflections (this may be remedied by slightly
tilting the filter) and lead to strain birefringence
in polarized light and ICT.
Fig. 9 Filter holder (intermediate unit), with lamphousing for
max. 4 filters, dia. 50 mm (when lamphousing 106 is used, only
1 thick or 2 thin filters can be inserted)
Filter magazine*
The best way to accommodate filters is there-
fore in the filter magazine (Fig. 10, 42.8 and 42.15):
Loosen the 2 fixing screws to remove the filter
magazine. It is easier to remove if the four
controls are operated. Put the filters into the
slots (without holders!) and tighten the clamp
screw. Always put the diffusing screen in the
position nearest the lamp . Put the label caps
(10.3) onto the corresponding switch rods and
align the lettering.
The filter magazine is more easily replaced if all
4 filters are tilted to one side first by pressing the
buttons. Finally, check that all 4 filters can be
switched in and out smoothly and tighten the
fixing screws. If thick filters get stuck, try putting
them in a different slot or altering their position
in the slot.
Interference filters must be inserted with the
bright reflecting side towards the light source!
