Leica M205 FA user manual Simple filter holders, Longer than 15 seconds, Without fluorescence

Simple filter holders

Simple filter holders

Three simple filter holders are included with the Leica M165 FC and the Leica M205FA. These filter holders have two empty openings for the observation beam paths. The third opening, to the illumination beam path, is closed.

ρρ Use this filter holder if you want to work briefly (no more than 15 seconds) without fluorescence illumination.

So that the filter holder is not heated, it must not block the mercury light for

longer than 15 seconds.

Safety Notes

ρρ If you want to block the mercury light for longer than that, activate the UV shutter.

ρρ	Use the filter if you want to change to trans-
	mitted light or incident light observation
	without fluorescence.
ρρ	Always place a simple filter holder into the
	empty filter changer positions in order to
	protect yourself from UV radiation and
	protect the system from dust.

•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.
