Abstract:
An extreme ultraviolet optical element is made by: providing an aqueous sol including a solid phase of titania-containing silica powder; forming the sol into a titania-containing silica shaped gel having a homogenous distribution of titania; drying the titania-containing silica gel to provide a dried titania-containing silica body; and heating the titania-containing silica body to a temperature to form glass body (18). An Independent claim is also included for a titania-containing silica glass body having a length greater than 10 cm, a width greater than 10 cm, a titania concentration of 6.5-7.5 wt.%, and a coefficient of thermal expansion (CTE) variation of less than 1 ppb/degrees C.
Abstract:
Methods of improving the direct bonding of articles are disclosed. Lithium can be incorporated into the composition of one of the articles and/or lithium can be added to a bonding surface by ion exhchange, absorption, ion implantation, coating, or deposition. Bonding is achieved without use of adhesives or high temperature fusion. The invention is useful for bonding a wide variety of articles together such as optical components, optical fibers and articles having different coefficients of thermal expansion or refractive indices.

Abstract:
A lens array and a method for fabricating a lens array that is relatively flat and has useful lenses with relatively uniform sag heights are described herein. In one embodiment, the lens array includes a one-dimensional array of useful lens and two sacrificial lens each of which is formed next to an end of a row of the useful lenses. In another embodiment, the lens array includes a two-dimensional array of useful lens and a plurality of perimeter sacrificial lens each of which is formed next to an end of a row or a column of the useful lenses. In yet another embodiment, the lens array includes an array of useful lenses and a glass region (including possibly a glass matrix) located within a opal border and outside a opal region that surrounds the useful lenses.
Abstract:
A print press system and a method are described herein that print an electronic circuit onto a material (e.g., glass substrate, plastic film, plastic film-glass substrate laminate). In exemplary applications, the print press system can print an electronic circuit onto a material to form, for instance, a flexible Liquid Crystal Display, a retail point of purchase sign and an e-book.
Abstract:
A fiber array includes a substrate (100) made of a soft drillable material and a plurality of holes (104) drilled through the substrate for holding a plurality of glass fibers (200).
Abstract:
This colloidal silica soot is a byproduct of chemical vapor deposition processing of fused silica or ultra low expansion glasses. The colloidal silica byproduct is referred to as "soot". Retaining the same physical properties as the parent glass and having a spherical morphology, the colloidal silica soot is an ideal candidate for final polishing applications of optical fluoride crystals 44, and particularly for optical fluoride crystals 44 such as calcium fluoride which have high transmission levels to below 300nm light such as produced by excimer lasers. The soot has a large particle size and spherical shape when compared to conventional colloidal or fumed silica
Abstract:
Disclosed are photo or electron beam curable polymerizable compositions, and preparation thereof and devices containing such cured material. The composition contains completely or substantially completely hydrogenated hydrocarbon-based material completely free or substantially free of carbon-carbon double and triple bonds containing photo or electron beam curable terminal or pendant groups, low-outgassing photoinitiators, an optional viscosity adjustment component and an optional filler. The composition is visible light, UV or electron beam curable. It cures into a low-modulus, low outgassing polymer material. The composition can be used as an adhesive, sealant or lens potting material. It is ideal for use in lithographic tools and other optical devices involving deep or vacuum ultraviolet radiations, in particular, as lens potting materials for 248 nm, 193 nm and 157 nm lithographic tools, as well as other optical devices involving using high fluence irradiation.
