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".
