Polished Sapphire Substrates and Windows
Valley Design produces standard and custom lapped or polished Sapphire wafers in all common orientations including A, C and R-plane Sapphire. Valley also provides ultra-thin polished Sapphire substrates and wafers. The size of Sapphire that can be polished is limited only by the material availability. Sapphire blanks up to 12″ diameter can be lapped, optically polished, diced and CNC machined. Holding precise tolerances as well as flatness, and parallelism is critical for many applications.
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″.
