Opto-electronic device esp. laser range finder - has transmitter with optical system sighting device and opto-electronic receiver

摘要

Receiver optical system operates together with the sighting device, with the optical system consisting of a collimator with a ray splitter consisting of prismatic elements. A stop forming the receiver input is in the optical system one focal plane, and a measurement or recording device is in its other focal plane. Focal planes representing the two image planes of the receiver optical system (5) coincide with an outer limiting surface (14, 15) of the ray splitter (7), which also serves as support for the receiver stop (16) and a test mark (17). The common surface of the prism is provided with a selective dichroitic filter.
