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 accord-
ance 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-level eye hazard), in particular for
deliberate ocular exposure. 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 radi-
ation.
