A lens barrel is the classic thin-wall rotational part: bore coaxiality and face perpendicularity decide the assembled optical performance, while the wall thickness itself limits the available cutting parameters. These have been a mainstay since the company entered the optical sector.
Optical work spans infrared detection components, chromatography parts and the mechanical components mating to various lens assemblies. Customers include Carl Zeiss, Leica, Edmund Optics and Janos.
