Laser Guide

The Laser Guide built into the TS16 G instrument produces a visible red laser
beam which emerges from the front side of the telescope.
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,
inherent safety margin in the maximum permissible exposure to laser radi-
b)
ation (MPE)
natural aversion behaviour for exposure to bright light for the case of vis-
c)
ible radiation.
