Leica M205 FA user manual Filter Changer, Simple filter holders also protect the system from dust

Filter Changer

The patented FLUOIII® filter system consists of a filter changer for barrier and excitation filters, a UV shutter that can be activated/deactivated, and a filter insert for a filter holder with your choice of filter.

The filter changer can hold a total of 4 filter sets. The filter sets for fluorescence are labeled (see Page 118). All filter sets are equipped with a tran- sponder for automatic filter detection and can also be used with the motorized Leica M205 FA.

The scope of delivery of the Leica M205 FA and Leica M165 FC includes three simple filter hold- ers without fluorescence for empty filter posi- tions and transmitted or incident light observa- tion without fluorescence. These filter holders have two empty openings for the observation beam paths. The third opening, to the illumina- tion beam path, is closed.

•If you are using fewer than four filter holders with fluorescence filters, always

insert the included simple filter holders with closed illumination beam path into the avail- able positions. Otherwise, there is a risk of danger to the eyes from direct UV radiation from the third beam path.

Filter sets for fluorescence

The filter sets for fluorescence contain, on one filter holder, two barrier filters to the visual beam paths and one excitation filter to the illu- mination beam path. The fluorescence filters have a transponder with the specific filter data for use with the motorized Leica M205 FA. The filter sets are labeled (see Page 118).
