ABSTRACT:
A laser protection device comprising a plurality of edge filters for receiving an incident beam and progressively separating the desired optical energy from the laser energy contained in the beam. The first edge filter receives the incident beam and provides a first reflected beam and a first transmitted beam. One of the beams provided by the edge filter comprises a relatively high percent of desired optical energy and the other of the beams provided by the edge filter comprises a relatively high percentage of laser energy. The other edge filters are arranged in series to similarly progressively reduce the percentage of laser energy contained in the beam.
