摘要： A lens array and a method for fabricating the lens array are described herein. The lens array is made from a photosensitive glass plate containing a relatively small amount of a photosensitive agent (e.g., silver, gold or combination thereof) such that when the photosensitive glass plate is subjected to an exposure step, a heat treatment step and an optional ion exchange step it becomes a glass composite plate that includes glass regions which are lenses and also includes an opaque opal region located around each of the lenses. The lens array has clear, colorless lenses exhibiting greater sag heights than those yellow lenses found in a traditional lens array made from the traditional photosensitive glass plate which was subjected to similar exposure, heat treatment and ion exchange steps.

C. under reducing conditions. The method comprises subjecting such a glass having a base composition which contains at least 1% by weight Li.sub.2 O, at least 2% by weight Na.sub.2 O, and at least 6% by weight Li.sub.2 O+Na.sub.2 O+K.sub.2 O to an ion exchange reaction, wherein lithium ions, and potassium ions, when the latter are present in the composition, in the glass surface are exchanged with sodium ions from an external source, prior to the reduction heat treatment.

摘要： This invention is directed to a method of forming optical devices composed of a photonucleable, crystallizable, lithium silicate glass body having at least one glass lens integral with and rising above at least one surface thereof, the lens being surrounded by a crystallized glass matrix, and optical devices produced by such method. The inventive method comprises subjecting the crystallized body to an ion exchange reaction wherein sodium and/or potassium ions from an external source are exchanged for lithium ions within the surface of the glass lens, the exchange reaction being conducted at a temperature of about 25.degree.-125.degree. C. above the annealing point of the glass for a time sufficient to produce a lens having an axial height in excess of 100% greater than that of lenses produced solely by selectively crystallizing a photonucleable, lithium silicate glass body.

摘要： A method for modifying surface coloration in silver halide-containing photochromic glasses developed by thermal reduction treatments is described, which method comprises subjecting the glass, prior to the coloring thermal reduction treatment, to a silver ion exchange treatment during which silver ions are introduced into at least a portion of the surface of the glass article. Subsequent thermal reduction of the silver-containing surface portion of the glass provides novel colors and/or color patterns therein.

摘要： Method of patterning or forming color gradients and/or designs on a glass surface are disclosed. Patterns are formed by depositing a film of metal on at least one surface of the glass; forming a layer of photoresist over the metal; exposing the article to light through a mask which contains a desired pattern; developing the piece to remove the exposed photoresist to reveal the underlying metal; removing the underlying metal to reveal the underlying glass; and removing the unexposed photoresist to reveal the underlying metal. To form color gradients or color patterns, the glass article is further treated in hydrogen at a temperature in the range of 300-600.degree. C. to effect the desired surface coloration.
