Patent number: 7241559Abstract: 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.Type: GrantFiled: October 3, 2003Date of Patent: July 10, 2007Assignee: Corning IncorporatedInventors: Nicholas F.

Patent number: 6844277Abstract: The present invention relates generally to UV (ultraviolet) photosensitive bulk glass, and particularly to batch meltable alkali boro-alumino-silicate glasses. The photosensitive bulk glass of the invention exhibits photosensitivity to UV wavelengths below 300 nm. The photosensitivity of the alkali boro-alumino-silicate bulk glass to UV wavelengths below 300 nm provide for the making of refractive index patterns in the glass. With a radiation source below 300 nm, such a laser, refractive index patterns are formed in the glass. The inventive photosensitive optical refractive index pattern forming bulk glass allows for the formation of patterns in glass and devices which utilize such patterned glass.Type: GrantFiled: March 15, 2002Date of Patent: January 18, 2005Assignee: Corning IncorporatedInventors: Nicholas F.

Publication number: 20040241557Abstract: Disclosed are masks and mask blanks for photolithographic processes, photosensitive materials and fabrication method therefor. Photosensitive materials are used in the masks for recording permanent pattern features via UV exposure. The masks are advantageously phase-shifting, but can be gray-scale masks having index patterns with arbitrary distribution of refractive index and pattern dimension. The masks may have features above the surface formed from opaque or attenuating materials. Alumino-boro-germano-silicate glasses having a composition comprising, in terms of mole percentage, 1-6% of Al2O3, 10-36% of B2O3, 2-20% of GeO2, 40-80% of SiO2, 2-10% of R2O, where R is selected from Li, Na and K, and expressed in terms of weight percentage of the glass, 0-5% of F, can be used for the mask substrate.Type: ApplicationFiled: May 29, 2003Publication date: December 2, 2004Inventors: Robert A.
