Sapphire Optics

  • 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. Customized windows are offered upon customer's request, and the optics with anti-reflection and other thin film coatings are also available. 
  • Single crystal sapphire are ideal for demanding applications and harsh environments because of their extreme surface hardness, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamond, which offers an excellent scratch resistance. Sapphire crystals glass is high transparency with transmission range at 0.15 to 5.5μm. Hangzhou Shalom EO provides the customized sapphire watch windows, the flat and spherical windows and other special shaping windows are available upon customer’s request.
  •  Single crystal sapphire prisms are ideal for demanding applications (such as laser systems) and harsh environments 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 diamond and, because of their structural strength, sapphire crystal lenses can be made much thinner than other common materials. Chemically, sapphire is single crystal aluminum oxide (Al2O3) and is useful in a transmission range from 0.15 to 5.5μm. Customized lenses are offered upon customer's request.

  •  Sapphire and Ruby ball and half-ball (hemispherical) lenses feature a very short back focal length with the convenience of a flat surface for easy mounting. Sapphire features a high index of refraction and excellent broadband transmission characteristics. Ruby half-ball lenses are easier to see and therefore easier to handle for physical applications. The lenses are very chemically stable and are great for severe environments, high temperature applications, and applications requiring high melting points. Typical applications include fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems.
  • Domes needs to be both high transmission as well as durability, sapphire is a excellent selection for its good mechanical properties and good transmission at MWIR of 3-5 mirco.  Shalom EO provide the sapphire domes used in aerospace and defense industry and the domes used in missile and reconnaissance & surveillance applications.
