UV-Guard™

White light arc lamps produce UV and IR radiation that can damage microdisplay panels, polarizing foils and other components used in projection display systems. Optics Balzers' UV-Guard™ filters block these wavelength ranges of the lamp’s spectrum while providing excellent transmission for visible light. Manufactured with Optics Balzers’ sputter coating process, UV-Guard™ filters provide the highest degree of spectral stability, both at high operating temperatures and under varying environmental conditions. UV-Guard™ filters withstand the highest light flux levels from high power UHP and Xenon arc lamps and do not affect colors of the transmitted visible light.
