Laser beam

Distance, Measurements without Reflectors
The EDM module built into the product produces a visible laser beam which emerges from the
telescope objective.
The laser product described in this section is classified as laser class 3R in accordance with:
•
IEC 60825-1 (2014-05): “Safety of laser products”
Direct intrabeam viewing may be hazardous (low eye hazard level), in particular for deliberate
ocular exposure. The beam may cause dazzle, flash-blindness and after-images, particularly
under low ambient light conditions. The risk of injury for laser class 3R products is limited
because of:
a
)
unintentional exposure would rarely reflect worst case conditions of (e.g.) beam alignment
with the pupil, worst case accommodation,
b
)
inherent safety margin in the maximum permissible exposure to laser radiation (MPE)
c
)
natural aversion behaviour for exposure to bright light for the case of visible radiation.
