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.
