ABSTRACT:
A device for protecting an optical component from a laser beam. The device includes a carrier which is light-pervious in a predetermined spectral range and is positionable in an expected path of a laser beam directed to the optical component; and a metal oxide film applied to the carrier. The film is light-pervious in the same spectral range and is oriented such as to intercept a laser beam directed to the optical component.
