Sapphire optical window YT-263

Place of Origin: Jilin, China Brand Name: YT Model Number: YT-263 Use: Optical Shape: PLANO Substrate: Sapphire Dimension(mm): Customer's request Flatness: 1/4 lambda S/D: 60/40 Parallelism (arcmin): ≤3.5 Clear Aperture (%): ≥95 Wavelength Range (μm): 0.2 - 5.5 Polished: Yes Coated: Yes Application: For Watch Sapphire Windows Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with mproved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al203) and is useful in a transmission range from 0.2 -5.5um.
