Industry & Occupation
Classification
Summary
A technical job that finely adjusts the focal position of lenses and optical components in optical instruments and measuring devices to optimize product performance.
Description
Focus adjustment workers assemble parts such as lenses and prisms used in optical instruments and measuring devices, then adjust the optical path to optimize the focal position. For equipment like microscopes, cameras, telescopes, and measuring devices, they use interferometers, laser measuring instruments, MTF measuring devices, etc., to measure focus and aberrations, performing fine clearance adjustments and lens spacing adjustments. High attention to detail and manual dexterity are required, and they are also responsible for quality inspections based on customer specifications and drawings, as well as creating calibration records. Work is often in clean room environments, requiring environmental controls such as temperature and particle management.
Future Outlook
Demand for precision optical instruments and measuring equipment is stable, and while work efficiency will improve with advances in automation, advanced manual fine-tuning skills will continue to be required.
