6. SAFETY PRECAUTIONS
6.1 . Rangefinder LRB 20000 is an optical-electronic device
emitting high-density pulses of invisible light at wavelength of
1.06 µm, characterized by the following dangerous factors:
- direct laser radiation;
- mirror-reflected laser radiation;
- diffuse-reflected laser radiation.
Direct and mirror-reflected laser radiation of the
rangefinder is dangerous for naked eyes at 1700 m distance
and less.
Diffuse-reflected laser radiation is dangerous at 0.43 m
distance from reflecting surface.
Optical devices increase these distances in accordance with
optical device magnification ratio.
Laser energy at the output objective lens of the rangefinder
exceeds permissible level for skin by 16% and reaches
permissible level at 3.77 m distance from the rangefinder.
