Standard Coatings

LightPath offers a variety of multilayer broadband coatings to reduce the back reflection from a nominal 6% for uncoated lenses. The choice of which AR coating is appropriate depends on the type of glass the lens is made from and the wavelength at which the lens will be used.

Custom coatings are available upon request

Infrared Laser Collimation Lenses

Our infrared collimating lenses transmits very well from 2-14μm. These lenses are ideal for the collimation and focusing of quantum cascade lasers and other long wavelength laser sources. Standard and custom AR coatings are available.
