OPTICAL SYSTEM FOR HIGH SPEED LASER SCANNER

摘要

Disclosed is an optical system for a high speed laser scanner. An emission device of the present device comprises: a first light source which outputs a first laser beam of a first wavelength; a second light source which outputs a second laser beam of a second wavelength, different from the first wavelength; a prism which provides the first and second laser beams to an emission unit; and the emission unit which changes routes of the first and second laser beams respectively, and emits the first and second laser beams wherein the first and second laser beams are inputted from the prism.
