Crystran Ltd

We are optical engineers specialising in fabricating components from IR and UV materials, mainly crystal or innovative glasses used for their particular transmission properties, from which we derive the name of our company.

You can see a full list of the materials we work with on our materials page. This includes well-known materials for use in the IR spectrum such as Germanium and Zinc Selenide, but also more exotic crystals such as KRS-5 and Cesium Iodide providing IR transmission up to 50 um. For deep-UV applications, we offer a wide variety of fluoride salts such as Calcium Fluoride and Magnesium Fluoride, all cut and precision-polished under one roof. Additionally, we work with a whole host of glass types suitable for visible / near-IR and UV optics. Filter glasses, high index glasses or even the commonly found BK-7 can all be supplied.
