1535nm Laser Ranging Module 15km
We provide a 1-year warranty on all devices, complemented by lifetime technical after-sales assistance to ensure long-term operational efficiency for your business.
DESCRIPTION
The LRF1525C-02 laser rangefinder utilizes 1535nm erbium-glass laser technology, supporting both single-pulse and continuous ranging modes (adjustable frequency: 1–10Hz). It features distance filtering, front/rear target indication, and self-diagnostic functions (monitoring internal voltage, temperature, etc.). This product is a transceiver lens, suitable for long-distance differential ranging, with a minimum ranging distance of not less than 50 meters.
