For Co2 laser use we offer ZnSe (Zinc Selenide) lenses with low absorption, anti-reflection coatings. ZnSe has a natural reflectivity of 17% at normal incidence so an antireflection coating is needed to stop back reflections

A wide range of standard size lenses are available for most CO2 laser machines of European, US, or Japanese origin. These are cost effective replacements when compared to the OEM part, and are of equal or better quality.

Also available are lenses of non-standard dimensions, such as extra thickness for high gas pressure use, or specific focal lengths, that might be used to complement a beam expander for example. Ask for our freeware calculator for calculating lens thickness..

Lenses are available in mounts where needed.

We also work with other infra red transmitting materials such as Ge, BaF2, CaF2, NaCl, KCl and Silicon. Some of these materials can be used with out anti-reflection coatings which makes them very cost effective. Optical design software allows multi element and multi-wavelength lens designs. Beam delivery design using "Gaussian beam" propagation software complements Zemax optical design.
