12km Eye-safe Laser Rangefinder Module

STA-LRB1220X laser ranging module is equipped with Stalaser’s independently developed 1535 nm erbium-glass laser assembly. It features a compact structure, low power consumption, and a ranging capability of up to 12km for typical NATO targets. With stable and reliable performance, it facilitates system integration and secondary development, making it an ideal core component for various compact long-range electro-optical systems.

Range performance:12000m (2.3×2.3m NATO Targets),20000m (Maximum range)

Ranging accuracy ± 1m

Measurement accuracy ≥ 98%

Weight ≤ 350g

 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.
