ABSTRACT:
A viewing window is equipped with a selective attenuator for a harmful incoming laser beam. The attenuator principally employs a holographic optical element which selectively deflects the laser beam where it may be absorbed or further deflected. Ordinary light passes undeflected so that it may be processed by optical equipment or a viewer.
