1535nm Eye-safe Laser Ranging Module-LRF1830C

The LRF1830C laser ranging module is a long-range laser rangefinder based on the 1535nm glass laser independently developed by Erdi. It adopts the single-pulse TOF (Time of Flight) ranging method, and the range can reach ≥18km for an objective of 4m×6m. It is composed of a laser, a transmitting optical system, a receiving optical system, and a control circuit board. Through the RS422 serial port and embedded software, it is convenient for users to conduct secondary development. Its main functions include single ranging and continuous ranging, three-target ranging, front and rear target indication self-check function (including: current APD temperature, high voltage value, internal voltage, and blind zone value), and standby wake-up function.
