High Quality Sapphire Wafer

Realpoo Optics provides sapphire wafers and substrates of various specifications in different crystal directions, thicknesses, processing accuracy requirements.  Specifications: Material : Sapphire AI2O3 Diameter : 2-200mm Dimension Tolerance :+0.0/-0.1mm Surface Quality :60/40 , 40/20 , 20/10 , 10/5 Angle Tolerance :<3 arcmin Double sides polishing Orientation : C plane Bevel : Protective bevel as needed Sapphire (molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission and good chemical stability. Widely used in many fields of industry, national defense and scientific research (such as high-temperature infrared windows, etc.). At the same time, it is also a widely-used single crystal substrate material. It is the preferred substrate for the current blue, violet, and white light emitting diode (LED) and blue laser (LD)…
