OPTICAL COMPONENT FIXING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an optical component fixing structure for fixedly bonding an optical component such as a lens to a device casing with high accuracy.SOLUTION: An optical component having a through-hole in parallel to an optical axis is fixed between a casing wall in the casing perpendicular to a direction of the optical axis and a casing wall facing the former casing wall by double-sided adhesion using adhesive filled into the through-hole.
