Thin fused silica polishing, fused silica substrates, windows, wafers, plates

Fused Silica substrates are now available in 300mm diameter and .030″ thick, as well as natural Quartz substrates 3.00″ in diameter and .001″ and .003″ thick. These are supplied to research facilities in the electro-optical field as well as for many other applications.

Most optical materials can be processed in sizes as large as 12″ square or 12″ diameter. Thickness tolerances can be as tight as ± .0001″, with flatness to 1/4 lightband, and parallelism to 50 millionths of an inch. Custom windows in any size, shape, thickness or surface finish are also readily available.

Valley Design offers a complete line of lapped, polished and diced substrates, flat polished optical pieces, Sapphire, Glass and other materials. Super-polished optical surface finishes < 10/5 scratch/dig (5-10 Angstroms) and as thin as, 0.0005″ are available from Valley. Valley Design also provides precision machining services such as wafering of optical materials, precision lapping and polishing of various materials including fused silica, quartz, crystals, ceramics, and metals and delivers coated optics to the optics, semiconductor, medical and aerospace industries, OEM manufacturers and research laboratories.
