ABSTRACT:
This invention relates to light transmitting filters comprising: (a) a light absorbing layer of material having a front surface and a back surface, (b) transparent microspheres embedded in the light absorbing layer and contacting the front surface of the light absorbing layer with portions of the microspheres protruding through the back surface of the light absorbing layer for transmitting light through the light absorbing layer, and (c) a conformed layer of optically clear material having a front surface and a back surface wherein the front surface of the conformed layer is in contact with and conforming in shape with the protruding portions of the microspheres, and wherein the back surface of the conformed layer has a textured finish. The invention also relates to methods of making these light transmitting filters.
