Leica M205 FA user manual Radiation from reaching the eyes, Beam paths to protect the eyes

Safety Instructions (cont'd.)

•Direct contact with eyepieces is a poten- tial transmission method for bacterial

and viral infections of the eye.

The risk can be kept to a minimum by using personal eyepieces for each individual or detachable eyecups.

Light sources: Safety regulations Protective measures of the manufacturer:

ρρ UV protection screen in front of the speci- men plane prevents the user from looking directly into the UV rays.

ρρ	Dummy filter carriers in the free positions
	of the rapid filter changer prevent direct UV
	radiation from reaching the eyes.
ρρ	UV filters are installed in the observation
	beam paths to protect the eyes.
ρρ	The stray-light protection on the lamp
	housing prevents irradiation of the hands.

Warning

•UV radiation could damage the eyes. Therefore:

ρρ	Never look into the light spot on the speci-
	men plane without a UV protection screen.
ρρ	Never look into the eyepieces if no excita-
	tion filter is in the beam path.
ρρ	Fill empty filter positions with dummy filter
	carriers (e.g. M165 FC).
ρρ	Do not select a white, strongly reflective
	background for the specimen.
