We are always available to advise on the best choice of materials. There are no menus on our telephone line, if you call you will speak to someone who can direct your enquiry immediately.

 

Make to Order: The very nature of the wide range of materials and applications in the IR, UV and visible regions of the spectrum means that most of our work tends to be custom made to specification. We manufacture in research and prototype quantities and also for production. If you have planning time, then we can make exactly what you want to your drawing or specification.

Purchase from Stock: Some lenses and windows are in constant manufacture are nearly always available for immediate delivery. If you need a component quickly then look up our Stock Optics page.
