Polished Sapphire Wafers and Substrates

Sapphire Wafers image

Sapphire wafers and substrates are available in all orientations with the more common ones being R-plane (1-102), A-plane (11-20) also referred to as 90-degree Sapphire and C-plane (0001) referred to as 0-degree or basal plane Sapphire. Valley also stocks Silicon on Sapphire (SOS) wafers.

Transmission Curve and Technical Data Sheet

Because it is an anisotropic hexagonal/rhomohedral crystal, some properties depend on the crystallographic direction and these directions are specified relative to the optical C-axis.

Sapphire wafer and substrate applications include:
