1535nm 3KM Eyesafe Laser Ranging Module 3000m
The LRF0308C eyesafe laser rangefinder moduleproduced by Sheng Fei Guang Su,utilizes a selfdeveloped 1535nm Diode Pump Solid State microchip laser. With a NATO target ranging capability of 2.3m×2.3m and a range of ≥3000m, it packs a punch in a small package, measuring ≤ 48×30.5× 21 mm and weighing ≤32g. This product boasts stable laserdistan
ce measurement, self-testing, power-up, and temperature collection and reporting capabilities.Among its many features are
three-target ranging, target indication both before and after measurement, single and continuous ranging modes, baud rate settingand tracking of the cumulative number of laser launches. Additionally, it supports serial port update
programs and offers various installation options and electrical interfaces, excluding the shell.To further facilitate its integration into handheld portable equipment or multifunctional systems, the module comes equipped with
upper computer test software andcommunication protocols.
