Laser Target Designer&Laser Rangefinder -LDR40K1
DESCRIPTION
The LDR40K1 is a carefully crafted, lightweight, and compact Laser Target Designator and Range Finder, delivering remarkable stability and performance in real-world use. This device emits laser beams to a specified target and accurately calculates distance data by gauging the time it takes for the laser light to travel and return. Boasting a pulse energy of 40mJ or greater, along with a NATO target ranging ability of 4km or more, the LDR40K1 is perfectly suited for compact observation systems across airborne, maritime, and terrestrial photoelectric operations. To further enhance usability, we offer RS422 upper computer test software and communication protocols, streamlining the process of secondary development for our customers.
