きょうどうくみたてこう（そうがんきょうせいぞう）
Industry & Occupation
Classification
Summary
Assembles optical components and lens barrels of binoculars using dedicated jigs, performs optical axis adjustment and magnification inspection to achieve high-precision optical performance.
Description
A lens barrel assembler (binocular manufacturing) accurately assembles optical components such as objective lenses, eyepiece lenses, prisms, and lens barrels using dedicated tools and assembly jigs. After assembly, uses optical axis adjustment devices and inspection equipment to measure magnification, field of view, resolution, etc., and confirms whether they meet product specifications. Since even minute misalignments directly affect product performance, work in a clean room environment, including anti-static measures and cleaning, is essential. As part of quality control, they also identify causes of defects and develop countermeasures.
Future Outlook
With increasing demand for high-precision optical instruments, demand for precision assembly technicians is expected to remain stable. Amid advancing automation, workers with specialized manual skills will be valued.
