GZM Eye-Safe Laser Range Finder Modules

GZM-Modules are open frame eyesafe laser rangefinder OEM modules, designed for integration into electro-optical surveillance, targeting systems, weapon stations and thermal cameras for land, airborne and naval applications.

GZM-Modules have robust, lightweight frame which can withstand vibration shock and temperature extremes. To simplify the integration, laser transmitter is located in a sealed compartment and flashlamp visible light is filtered.

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