Polished sapphire wafers, disks and washers

We specialize in large and small thin plates, up to 12″ in diameter. Whether the material is Sapphire, Ceramics, Quartz, filters, or any other machineable material, this method will produce high quality parts.

The available crystal orientations are A-plane [1120], C-plane [0001] and R-plane [1102]. The minimum thinness possible, to a large degree, is dictated by the crystal orientation chosen.
