  • Patent number: 5005926
    Abstract: An interference filter is deposited on a high temperature transparent plastic film which passes normal incident radiation below 694 nm and reflects other wavelengths out to 1064 nm regardless of the angle of incidence of the laser radiation applied thereto. The interference filter is optically bonded directly onto a ballistic protective plastic substrate which transmits visible radiation thereby providing a laser shield having ballistic properties as well as laser radiation rejection properties. The ballistic protective plastic substrate may also contain absorbing dyes for absorbing laser radiation in the region of high sensitivity of 400 to 700 nm. The interference filter is then optically bonded directly onto the transparent ballistic protective plastic substrate thereby providing a protective laser shield having ballistic protection properties as well as hybrid filter properties both absorbing and reflecting laser radiation.
