    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.

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.
