6.6.3 Distancer, Measurements without Reflectors
General
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 (2007-03): "Safety of laser products"
•
EN 60825-1 (2007-10): "Safety of laser products"
Class 3R laser products:
Direct intrabeam viewing may be hazardous (low eye hazard level), in partic-
ular for deliberate ocular exposure. The beam may cause dazzle, flash-blind-
ness 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.
