Zoolied offers Sapphire(Al2O3) Crystal Glass Plate Sheet.
High Hardness Sapphire (Al2O3) is a superior optical material which is used for its excellent optical, chemical and physical properties for use in the UV, Visible and Infra-red regions. Sapphire Crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond. Sapphire is able to be cut thinner than alternative crystals due to its structural durability.
Sapphire is grown using a variety of methods. Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method.
Zoolied Inc. 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?
