DESCRIPTION
The LRF0410C eye safety laser rangefinder module is manufactured by ERDI TECH using a self-developed 1535nm Diode Pump Solid State microchip laser. It has a NATO target ranging capability of 2.3m ×2.3m with a range of ≥4000m. The dimention is ≤50mm×47mm×24mm and the weight is ≤58g. The product features stable laser distance measurement, self-test, power-up and temperature collection and reporting functions. It also includes three-target ranging, target indication before and after measurement, single ranging and continuous ranging modes, baud rate setting, cumulative number of laser launches tracking, serial port update program support, as well as various installation options and electrical interfaces without an included shell. Additionally, it provides upper computer test software and communication protocols to facilitate its use in handheld portable equipment or multifunctional systems. This module finds wide applications in fields such as laser distance measurement, unmanned airborne systems (UAS), optical pods, boundary monitoring.
