Product Description

Newport's UV Extreme™ ultraviolet filters have been specifically designed for the most severe environments where ultraviolet filters are used. UV Extreme filters are manufactured using all-dielectric thin-film designs featuring Newport's patented Stabilife® coating technology which produces highly dense, virtually indestructible films. These films are incorporated into a product design that employs a proprietary assembly process that eliminates organic materials which can degrade under very high temperature. UV Extreme filters have been qualified to operate at temperatures as high as 400 °C with no degradation of spectral performance or physical damage. UV Extreme™ filters are available on a custom basis for OEM applications in sizes, bandwidths, and at wavelengths as required by the application.
