Leica MZ16 F – Safety concept 9
1.3 Light source: safety instructions
Precautions by the manufacturer
– UV protection screen in front of the specimen
plane prevents the user from looking directly
into the UV rays.
–
Simple filter holders (that have only two open-
ings for the observation beam paths) in the avail-
able positions of the rapid filter changer prevent
direct UV radiation from reaching the eyes.
– UV shutter (which can be activated/deacti-
vated) prevents direct UV radiation from reach-
ing the eyes.
– UV filters in the observation beam path protect
the eyes.
– The stray-light protection on the lamp housing
prevents irradiation of the hands.
Warning
UV radiation can harm the eyes.
Therefore:
– Never look into the light spot on the specimen
plane without a UV protection screen.
– Always fill all of the filter positions with filter
holders.
– Fill empty filter positions with the simple filter
holders (which have only two openings for the
observation beam paths).
– Do not select a white, strongly reflective
background for the stage.
– Never open the lamp housing while the lamp is
switched on.
