18km Eye-Safe Laser Rangefinder Module

The STA-LRB1830X laser ranging module adopts Stalaser’s self-developed 1535 nm erbium glass laser assembly. Featuring a sealed three-proof housing and nitrogen-filled design, it delivers excellent waterproof, anti-fog and environmental adaptability. Compact, low-power and high-efficiency, it supports a 18 km ranging range for typical NATO targets. Stable, reliable and easy to integrate, it serves as an ideal core component for long-range electro-optical detection systems.

Range performance:18000m (2.3×2.3m NATO Targets),30000m (Maximum range)

Ranging accuracy:±3m(RMS)

Measurement accuracy:≥ 98%

Weight ≤850g

Main functions:

(1) Single ranging and continuous ranging;

(2) Responding to laser ranging commands, and can stop ranging at any time according to the stop command;

(3) Output distance data and status information once per pulse during distance measurement;

(4) It can report the cumulative number of transmitted laser pulses (no loss of power down);

(5) Distance selection, front and rear target indication;

(6) Self-test function.
