OPTICAL MODULE FOR LASER BEAM SCAN

摘要

Provided is an optical module for laser beam scan capable of compensating eccentricity of a mirror. The optical module for laser beam scan includes: a mirror mount; a rotary axis combined to the center of the mirror mount; a vibration member vibrating the end of the mirror mount forward and backward by being combined to one side end of the mirror mount; a mirror scanning a laser beam by reciprocal rotation movement around the rotary axis together with the mirror mount as being fixed to the mirror mount; a weight compensating eccentricity of the mirror by being arranged in at least either one side or the other side on the mirror mount located across the rotary axis.
