​​Sapphire Wafer Product Introduction​​

 
 

 

​​Sapphire Wafer Precision Cutting Diameter 60mm Thickness 3mm Optical Infrared Window​​

 

 

 

Sapphire wafer is a precision optical component fabricated from high-purity aluminum oxide (Al₂O₃) single-crystal material, with specifications of 60mm in diameter and 3mm in thickness. It achieves high-precision dimensional control through directional cutting techniques (e.g., laser cutting or diamond wire sawing), with surface roughness controlled to <0.5μm. The crystal orientation options include C-plane (<0001>), A-plane (0001), and M-plane (10-10), catering to diverse application requirements. Inheriting the inherent advantages of sapphire, sapphire wafer ardness (Mohs hardness of 9), high-temperature resistance (melting point of 2045°C), low thermal expansion coefficient (5.3×10⁻⁷/°C), and broad-spectrum transparency (0.15–5.5μm), making it a core material for advanced optoelectronics, semiconductors, and precision instrumentation.
