Abstract
A lens system for protecting high gain optical systems (eyes or equipment) from high intensity laser radiation includes a second mirror disposed on an exit lens, a first mirror formed by half silvering the inner surface of a focusing entry lens, and a medium such as sugar water containing aerosol particles of three-micron carbon, which induces ionization that will absorb the incoming laser radiation. One binocular embodiment uses the foregoing medium; a second binocular embodiment uses a solid lens material laden with aerosol particles.
