The 3 FL reflector slider has three stop positions, with the center position being equipped with
the FT 395 chromatic beam splitter for reflected-light brightfield. This short-wave chromatic
beam splitter permit "quasi" brightfield illumination. If required, this reflector slider position
can be upgraded in a filter set for UV excitation by the insertion of filters. The two other stop
positions contain complete fluorescence filter combinations specially selected by the user.
Excitation filters ( 3-18/4), barrier filters ( 3-18/6)
and chromatic beam splitters ( 3-18/2) can be
inserted and exchanged; the excitation and barrier
filters are accessible and can be exchanged after
unscrewing the retainer rings ( 3-18/5), and the
chromatic beam splitter after removing the base
plate (3-18/1) and loosening the mounts (3-18/3).
The coating of the chromatic beam splitter must
not be touched with your bare hands, and must
point to the excitation filter after insertion (i.e. in
the direction of the light source).
Depending on the application, various filter sets
(see overview) can be ordered and inserted into
the reflector slider.
