Description
- The hardest of the oxide crystals
- Excellent transparency and thermal properties
- Chemically inert and insoluble
- Can be safely made much thinner than windows from glass or other crystals
Single crystal sapphire combines excellent optical, physical and chemical properties. Chemically inert and almost insoluble, sapphire in many ways is superior material for windows. It is transparent from 150 nm up to 6 mm in the middle infrared. Sapphire exhibits anisotropy in many optical and physical properties. Difference in index of refraction in orthogonal directions is 0.008.
