Sapphire (Al₂O₃): Boasts high hardness and thermal resistance, transmitting UV (150nm) to IR (6μm). Used in laser cavity plates, optoelectronic windows, and LED substrates; excellent chemical stability.
Sapphire is a single crystal aluminum oxide (Al2O3).Its Mohs hardness is 9,it is one of the hardest materials.Sapphire has good mechanical strength,and it is also transparent from visible to IR spectrum.So,it is always used as window material where scratch resistance is required.
Sapphire Window is an optical component crafted from sapphire material. It boasts a transparent range of 180 - 4500 nm, enabling transmission of light from the ultraviolet to the infrared spectrum. At 1000 nm, its refractive index is 1.755, contributing to its distinctive optical performance. Sapphire’s inherent hardness and thermal stability further enhance its utility in demanding environments.
