Plurality of shield units for absorbing energy from a laser beam

Claim 1

A LIGHT-TRANSMITTING SHIELD FOR PROTECTING EYES AGAINST A BEAM OF LASER ENERGY OF SELECTED WAVELENGTH WHERE THE INTENSITY OF SAID BEAM IS SUFFICIENT TO DESTROY A HOMOGENEOUS FILTER SUBSTANTIALLY OPAQUE TO SAID ENERGY, SAID SHIELD COMPRISING A PLURALITY OF SHILED UNITS AND MEANS ADAPTED TO MOUNT SAID UNITS IN SEQUENCE BETWEEN A JASER AND THE EYES, SAID SHILED UNITS EACH BEING PRIMARILY ADAPTED FOR ABSORPTION OF LASER ENERGY OF AID SELECTED WAVELENGTH AND FOR RELATIVELY LESSER ABSORPTION OF VISIBLE LIGHT ENERGY OF OTHER WAVELENGTHS, SAID SHIELDS UNITS EACH BEING SUFFICIENTLY TRANSMISSIVE TO LASER ENERGY OF SAID SELECTED WAVELENGTH TO AVOID DESTRUCTION OF SAID UNIT UPON EXPOSURE OF SAID SHIELD TO A LASER BEAM OF SAID INTENSITY, SAID SHIELD UNITS EACH BEING ADAPTED TO ABSORB SUFFICIENT LASER ENERGY OF SAID SELECTED WAVELENGTH TO PREVENT DESTRUCTION OF SUBSEQUENT SHIELD UNITS IN SAID SEQUENCE UPON EXPOSURE OF SAID SHIELD TO A LASER BEAM OF SAID INTENSITY, SAID SHILED UNITS BEING ADAPTED TO COOPERATE IN SUBSTANTIALLY COMPLETELY ABSORBING A LASWER BEAM OF SAID INTENSITY AND SELECTED WAVELENGTH FOR PROTECTING THE EYES.
