optical instrument assembler
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.

The role shows moderate AI exposure (0.50 on a 0-1 scale) — some tasks are being automated but the role adapts. The most in-demand skills for the role include glass tempering, optical equipment standards, optical glass characteristics, types of optical instruments, quality standards.
Pay in the UK
UK: median £40,062 a year for Precision instrument makers and repairers (ONS ASHE 2025, full-time)
UK jobs are grouped differently; this is the closest UK occupation group (ONS SOC 2020 5224). ONS rates this estimate acceptable: it rests on a small sample, so treat it as a rough guide. 2025 provisional figures; ONS revises them a year later.
