We supply custom optical lenses consisting of single or multiple elements (doublets etc.) and for applications ranging from a simple collection of light to precise imaging, from machine vision optics to astronomical telescopes, and from the UV/visible wavelength range to the infrared.

We are confident we will be able to meet your specified requirements; custom lenses are available from 3.5mm to 500mm diameter, with surface quality up to 10-5 scratch-dig. We offer spherical, aspherical and freeform lenses as well as a range of AR coatings and substrates (including germanium and chalcogenides for infrared optics).
