Optical instrument assembler

Description

Optical instrument assemblers read blueprints and assembly drawings to assemble lenses and optical instruments, such as microscopes, telescopes, projection equipment, and medical diagnostic equipment. They process, grind, polish, and coat glass materials, centre lenses according to the optical axis, and cement them to the optical frame. They may test the instruments after assembly.
