Industry & Occupation
Classification
Summary
A technical job that measures and adjusts the focal length and optical performance of lenses to produce optical equipment with the specified performance on the manufacturing line.
Description
Lens focus adjusters are specialists who inspect the focal position and optical aberrations of lenses used in cameras and optical instruments using measuring devices (such as MTF measuring devices, interferometers, autocollimators, etc.), and perform fine position adjustments of lens groups and axis misalignment corrections. In a cleanroom environment, they operate small torque drivers and alignment devices, precisely assembling and adjusting based on design drawings and measurement data. High attention to detail and manual dexterity are required, and career paths to line supervision or production engineering departments are available depending on skill level.
Future Outlook
While demand for higher precision in optical components such as smartphones and autonomous driving sensors is expanding, the introduction of automatic adjustment and AI technologies is also advancing, requiring a balance between skilled craftsmanship and automation technologies.
