The LRI-5000 Rangefinder is a long range eye safe distance measurement system for measurement of distances up to 30 Km. It is fully sealed for extended outdoor operation. The laser source subassembly consists of an actively Q-switched Nd:YAG laser driving an optical parametric oscillator (OPO). Sample rate, laser beam divergence, and other parameters may be controlled from a terminal or from remote software.
