Abstract
An optical apparatus for focusing at least one image and optionally only one image of an object, said apparatus comprising a receiving surface and an optical imaging device between the image and the object to form an image of the object on the receiving surface. The imaging device comprising at least one glass body, at least a portion of which is a photonucleated opacified glass. The body has opposed surfaces, at least one of the surfaces having raised light focusing transparent optical pattern portions integral therewith and transparent channels connecting the raised transparent pattern portions to the surface opposed to the surface containing the pattern. The invention further comprises a method for focusing an image of an object on a receiving surface which comprises interposing an optical imaging device between the object and the surface to form an image of the object on the surface, said optical imaging device comprising a glass body at least a portion of which is a photonucleated opacified glass, said body having opposed surfaces, at least one of the surfaces having light focusing raised transparent optical pattern portions integral therewith, and transparent channels connect…
