6km Eye-safe Laser Rangefinder Module with Auxiliary Aiming Laser

STA-LRB60R Laser Range Finder Module integrates Stalaser’s in-house developed 1535 nm erbium-glass laser components. It features a compact structure and low power consumption, with a range capability of up to 6 km for typical NATO targets, delivering stable and reliable ranging performance. Equipped with a visible red dot laser for auxiliary aiming, it facilitates system integration and secondary development, making it an ideal core choice for various compact long-range electro-optical systems.

Range performance:6000m (2.3×2.3m NATO Targets),12000m (Maximum range)

Ranging accuracy ± 1m

Measurement accuracy ≥ 98%

Weight ≤ 75g

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.

(7)Laser calibration device with red dot.
