In
brief
Milltech machines precision optical components in Norwich, UK, including lens mounts, telescope parts, eyepieces and camera housings. Each is made to the fine tolerances and finishes optical assemblies require. We machine aluminium, brass and stainless, CMM-verified for repeatable accuracy, from prototype to production.
Overview
Optical components rely on precise geometry and clean finishes to hold alignment. We machine lens mounts, telescope components, eyepieces and camera housings in aluminium, brass and stainless steel, verified by CMM inspection.
