OPTICAL PATH SYSTEM COMBINING DUAL LIGHT INTO ONE AND LASER COLLIMATOR CONTAINING SAME

摘要

Provided are an optical path system combining dual light into one and a laser collimator containing same, comprising a first laser light source (3) and a second laser light source (4), and further comprising an agglutinate prism (2) formed by parallel agglutination of bottom faces of a first prism (2a) and a second prism (2b), wherein a transflective coating is plated on the bottom face of the second prism (2b), the first prism (2a) and the second prism (2b) are both right-angled prisms, emergent light of the first laser light source (3) is perpendicularly incident on the horizontally extending side face (2ba) of the second prism (2b), and emergent light of the second laser light source (4) is perpendicularly incident on a first perpendicular side face (2aa) of the first prism (2a). Good synthesis of dual light is ensured, and the mechanical structure of combining dual light into one is simplified. Moreover, because of good mutual superposition of the optical paths, debugging precision is substantially improved and the debugging becomes simple and easy. The illumination direction of a light source device such as a collimator or a flashlight can be adjusted and changed very easily by using an adjusting screw and an adjusting spring.
