Product Description
Product Overview
R-plane (1102) and C-plane (0001) sapphire wafers engineered for infrared (IR) and ultraviolet (UV) wavelength applications. These high-purity single crystal sapphire substrates offer exceptional optical and mechanical properties for demanding semiconductor and optoelectronic applications.
Crystal Growth Method
Our sapphire wafers are manufactured using the Kyropoulos method (Kr), an advanced crystal growth technique derived from the Czochralski process. This method enables production of large single crystal sapphire ingots with superior quality and consistency.
Available Crystal Orientations
R-plane (1102)
C-plane (0001)
A-plane (1120)
M-plane (1010)
N-plane (1123)
Custom orientations available
