MRLR-M Eye-Safe Laser Range Finder Module

MRLR-M is an open frame eyesafe laser rangefinder OEM module, designed for integration into electro-optical surveillance/ targeting systems and weapon stations for land, airborne and naval applications.

MRLR-M uses an efficient, eye safe diode pumped Er:Glass laser transmitter. This efficient laser source enables MRLR-M to reach measurement rates up to 5 Hz, which is an advantage for high speed targets.

To simplify the integration, laser transmitter is located in a sealed compartment. For easy boresighting, a boresight camera is provided. An optional laser pointer (IR or visible) can be replaced with the LED.

MRLR-M have built in test function and can be controlled via serial data interface RS422 or RS232.
