Ultra Thin Precision Glass for Precision Optics

Valley Design stocks and processes a wide variety of materials for information display and related applications. These materials come in standard sizes or can be machined to your custom specifications.

Services provided include precision lapping, polishing, dicing, edge/angle polishing, fiber array polishing, grinding and coating services and manufactures substrates, windows, wafers, wedges, hot and cold mirrors, glass rods and spacers, lenses, beam splitters, wave guides and other components. Wafers are routinely processed to SEMI specs up to 300 mm diameter, and larger by request.

Specialties are Ultra-Thin (as thin as 12.5 microns), Ultra-Flat (1/20 wave), Super polishing (<10/5 scratch/dig or 5-10 angstroms), tight tolerances (± 1 micron) and dicing as small as .005″ square. The end faces and outer diameters of many of these materials can also be optically polished.

· 1737F: Near zero alkali aluminosilicate composition glass, economically priced, withstands rigorous thermal cycles of polysilicate transistor processes. Used as substrates for electronic thin film circuits, polysilicate transistor processes, active matrix flat panel displays, microdisplays, TFTs and AMLCDs.

· B270/Crown Glass: High transparency material with uniform optical transmission characteristics in the visible spectrum as well as the IR and UV regions. Applications include display covers, high resolution scanners, optical elements for light sensors, optical windows, substrates, lenses.

· Borosilicates: (AF-45, D263, 7059, Borofloat) Low alkali glass featuring excellent thermal resistance, low coefficient of thermal expansion and optical transmission. These glasses can be used in thin film devices, LDC (active matrix), electroluminescent.
