Sapphire Wafers — 50.8mm to 200mm, C/R/M/A Orientation, DSP/SSP

Product Introduction:

Our sapphire wafers are available in diameters from 50.8mm (2") to 200mm (8"), with thickness ranging from 430μm to 1300μm depending on size. Offered in C, R, M, and A crystal orientations with double-side or single-side polished surfaces, these wafers feature exceptional surface quality (Ra ≤0.3nm), low warp (≤10μm), and tight TTV control(≤3μm), making them a reliable substrate for optoelectronic and optical applications.
