Sapphire Glass (Al2O3) is the second hardest crystal, after diamond, available. In its natural form, sapphire is a blue crystal but when it is produced synthetically for optical purposes it is transparent and boasts impressive optical properties including high hardness, high transmission, chemically resistance, high thermal conductivity, high dielectric constant, high modulus of rupture. It is therefore not surprising that High Hardness Glass sapphire is one of the most commonly used optical materials. Zoolied can supply a variety of High Hardness Sapphire optical components including windows, lenses, prisms and sapphire ground blanks. We can also provide uncoated and coated optics, with broadband antireflective (BBAR) coatings.
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? 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.
