Fused quartz, fused silica, optical materials thinned

Fused Silica

Fused quartz and Fused Silica polished substrates, plates, windows, sheets and wafers. Custom sizes with precision optical surface finishes to 10/5, can be shipped in just a few days. Common size windows are in stock.

Ultra-thin polished Fused Silica and Fused Quartz substrates 1"square and 2"square are available for immediate delivery from stock. Thicknesses are 0.002" (50 microns), 0.003" (75 microns), 0.004" (100 microns) and 0.005" (125 microns).

Other thicknesses in 1" and 2" square configuration available from stock are 0.010", 0.015", 0.020" (0.5 mm), 0.025" and 0.040" (1 mm).

3"(75 mm) diameter and 4" (100 mm) diameter Fused Silica substrates are semifinished and can be completed to any thickness in just a few days.

A surface finish of 20/10 and thickness tolerances of +/- 0.001", 0.0005", 0.0004", 0.0003" and 0.0002" are typically requested. Tighter tolerances are available on special order.
