We supply custom optical lenses consisting of single or multiple elements (doublets etc.) for applications ranging from a simple collection of light to precise imaging, from machine vision optics (machine vision cameras) to astronomical telescopes.

Custom lenses are available from 3.5mm to 500mm diameter, with surface quality up to 10-5 scratch-dig. Tight tolerances, supreme durability and a range of coatings, means that we can meet your specified requirements.
