Custom and Stock Optical Components
By the very nature of the wide range of materials and applications in the IR, UV and visible regions of the spectrum, most of our work tends to be custom made to specification. We manufacture in research and prototype quantities and also for production. Some lenses and windows are in constant manufacture and we also have a wide range of windows in stock as a result of production over-runs. Components that are nearly always available for immediate delivery are listed on our Stock Optics page. If you need a component quickly then look up our Stock Optics list, or email us and we'll search our stock.
