Alumina single crystal (Al2O3) deposition material

Since single crystal sapphire is used, gas generation during deposition is very low.

Since it uses high-purity (99.99%) sapphire single crystal (α-alumina), there are almost no voids in the material, which helps reduce gas generation during deposition. For anti-reflective coatings, hard coatings, and chemical-resistant coatings, please make use of our alumina deposition materials, which are produced in a consistent process from crystallization to cleaning. 【Product Features】 - High-purity Al2O3 single crystal (purity: 99.99%) - Medium refractive index (1.63 @ 550nm) - Appearance: Three standard shapes - crushed, cut, and crescent-shaped
