Zoolied offers 50.8mm T430um sapphire Glass Wafers 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 improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.
Zoolied offers in a variety of Sapphire Optics , such as Optical Sapphire rings, Step Glass, Sapphire Rod Lens and sapphire tubes. Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR). Looking for ideal optical sapphire Manufacturer & supplier? We have a wide selection at great prices to help you get creative. All the Sapphire Glass are quality guaranteed. Zoolied China Origin Factory of Sapphire Optics. If you have any question, please feel free to contact us.
