Optical Sapphire Polishing Services for Plates, Blanks and Windows

Optically Polished Large Sapphire Blanks and Windows

Valley Design has invested in tooling and fixturing to lap and optically polish large sapphire blanks, limited only by the availability of sapphire.

Sapphire blanks 12" diameter or 12"square can be processed. Holding precise thickness tolerances as well as flatness and parallelism, Valley Design can polish all common orientations, including "A" plane, "C" plane and "R" plane. Sapphire blank applications include covers, substrates, wafers, windows, flats and spacers. On "A" plane material, Valley routinely processes pieces to 0.002"; however, for special applications we have made parts as thin as .0005". Valley Design has extensive experience in processing materials of large geometry including metal, glass and Ceramic plates as large as 36" x 36".
