Abstract

PURPOSE:To contrive to make the titled device miniature and light in weight by decreasing the number of parts, by allowing an optical path splitter 11 to have a function for splitting a collimation light and a distance measuring light, and a function for splitting a transmitting light and a receiving light of the distance measuring light. CONSTITUTION:A collimation light reaches a distance measuring person through an objective lens 2, an optical path splitter 11, a focusing lens 4, an erecting prism 5, a focusing screen 6 and an eyepiece 7, along an optical axis A1. A transmitting light L0 from a distance measurement infrared light source 8 passes through the surface 11c of the optical path splitter 11 and reflected by the surface P3, and the dichroic mirror surface D, and emitted from the objective lens 2. A receiving light L1 reflected from a distance measuring object passes through the objective lens 2, reflected by the surface D of the optical path splitter 11, emitted from the surface 11D, passes through a rotary filter 12 and a filter 13, and made incident on a photodetector 10. A reference light L2 from a light source 8 is made incident on the photodetector 10 through a mirror 14. An exclusive prism for splitting the transmitting light L0 and the receiving light L1 becomes unnecessary, and the number of parts is decreased.
