Variable Range Simulator

Download Brochure

The VRS - Variable Range Simulator is a system used for range simulation and testing of Laser Designators and
Laser Range Finders (LRF) for accuracy and functionality.
The VRS can test LRFs operating in a broad range of wavelengths from 850nm to 1570nm, with the option of
selecting up to three discrete wavelengths to be incorporated into the VRS.
