IR Sapphire Windows
Sapphire (Al₂O₃) is an incredibly hard crystal (HK1370kg/mm2), second only to diamond. It has high mechanical strength, thermal and chemical resistance and is scratch resistant, making it very desirable for operating in harsh conditions. Sapphire windows can be made thinner than alternative crystals thanks to its structural integrity and can operate up to 2030⁰C. The material transmits between the UV and IR at 0.15-5.5µm, and has a high refractive index of 1.75..
Sapphire has applications where its strength and durability are required. This includes pressure optical windows, furnace viewports, submersible ROVs, gas and oil analysis, barcode readers and IR analytical devices.
Knight Optical supply a range of quality Sapphire optical components including IR Sapphire windows, Sapphire lenses, Sapphire prisms, and Sapphire blanks either from stock or bespoke custom made to your specification for a range of applications. Our current range includes Random Polarisation Sapphire that can be used for most applications apart from UV use. We also stock a range of C-cut/ Z-cut sapphire for UV applications. Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high quality standards.
