6.1. Rangefinder LRB 20000 is an optical-electronic device emitting high-density pulses of invisible light at wavelength of

1.06µm, 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.

10.5.4.During in-service maintenance, the cycle life of the range finder may not be spent by more than10 measurements.
