| Brief Introduction
SinoSi¨s glass wafers and substrates (Fused Silica, Soda Lime, BK7, B270, D-263, Sapphire, Quartz, Borosilicate Glass and other glasses), are available in sizes ranging from 76mm (3") up to 300mm (12") with options for a notch or one or two flats. The surfaces can be opaque or polished on one or both sides with chamfered edges. Custom wafers can be supplied to special thicknesses with tight tolerances including "ultra-thin" - 0.001" (25 microns) thick.Edges can be optically polished or rounded. Wafer cassette packaging available.
