4.4 Eyepieces
Always use eyepieces with the same magnification for both eyes. These are simply
placed on the tube sockets after first removing the protective plastic caps. There is no
fixation possibility. You should always make sure that the lenses are not touched with
your bare fingers and that no dust enters the openings.
4.5 Color filter
A blue color filter is already part of the condenser. It is screwed to the bottom of the
condenser by means of a ring holder. It can be removed at any time. To use suitable
filters without this retaining ring, they can simply be placed in the ring holder of the field
lens.
4.6 Condenser
The object stage should best be brought into the uppermost position using the coarse
drive. With the focus wheel of the condenser one must now bring the condenser carrier
into a middle position. This way, the condenser can be inserted into the condenser
carrier at the appropriate position and fixed with the locking screw. The scale should
be readable from the front. Avoid touching the optical lenses with your bare fingers.
