Leica M-series User Manual 7
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:
UV protection screen in front of the speci-
ρ
men plane prevents the user from looking
directly into the UV rays.
Dummy filter carriers in the free positions
ρ
of the rapid filter changer prevent direct UV
radiation from reaching the eyes.
UV filters are installed in the observation
ρ
beam paths to protect the eyes.
The stray-light protection on the lamp
ρ
housing prevents irradiation of the hands.
Warning
•
UV radiation could damage the eyes.
Therefore:
Never look into the light spot on the speci-
ρ
men plane without a UV protection screen.
Never look into the eyepieces if no excita-
ρ
tion filter is in the beam path.
Fill empty filter positions with dummy filter
ρ
carriers (e.g. M165 FC).
Do not select a white, strongly reflective
ρ
background for the specimen.
