1.6.2 Distancer, Measurements with Reflectors
The EDM module built into the product produces a visible laser beam which
emerges from the telescope objective.

accordance with:
•
IEC 60825-1 (2014-05): “Safety of laser products”
These products are safe under reasonably foreseeable conditions of operation
and are not harmful to the eyes provided that the products are used and
maintained in accordance with this User Manual.

1.6.3 Distancer, 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 particu-
lar 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 radi-
ation (MPE)
c
)
natural aversion behaviour for exposure to bright light for the case of vis-
ible radiation.
