Pulsed laser range finders. (Instruments).


This rugged, versatile and high performance line of non contact pulsed laser range finders range finder

Instrument used to measure the distance from the instrument to a selected point or object. The optical range finder, used chiefly in cameras, consists of an arrangement of lenses and prisms set at each end of a tube.
