Polished Sapphire Substrates and Windows
Polished Sapphire blanks, substrates and windows are processed to extreme tolerances as thin as 12.5 microns by Valley Design.
The size of Sapphire that can be polished is limited only by the material availability. Blanks 12" diameter or 12" square can be lapped and polished. Keeping precise tolerances as well as flatness and parallelism, Valley Design can polish all common orientations including "A", "C", and "R" plane Sapphire.
Sapphire blank applications include covers, substrates, wafers, windows, flats and spacers. On "A" plane material, we routinely process pieces to 0.002"; however, for special applications we have made parts as thin as 0.0005".
Valley Design is an ISO 9002 Certified company, with nearly 30 years of experience performing precision lapping and polishing materials. Large geometry substrates, wafers, and windows of Glass, Quartz, Fused Silica, metal, and Ceramic plates as large as 36" x 36" are available to tolerances within microns.
