Abstract
A lens array ( ) has a plurality of frusto-spherical convex lenses ( ), formed in an optical entry surface ( ) and an optical exit surface ( ), focusing light rays ( ) near the center between each lens pair ( ) in an area ( ) where the laser energy is focused sufficiently to induce vaporization resulting in aerosol breakdown which will absorb 99% or more of the laser energy, and thereby protect high gains optical equipment or eyes from optical damage.
