High purity Other Sapphire Window Products

As shown by the last decade of the development of the sapphire industry and the corresponding application fields, interest in both constructional and functional sap-phire has grown to a great extent. One may even say that such a “renaissance” of sapphire is one of the most significant tendencies in modern materials...

Transparent Smooth Sapphire Window As Fingerprint

Sapphire windows are applied in gas cryostats and helium microstats with D (12…25) × 2 mm, sealed in metallic flanges or gasketed in the sockets of devices. Copper gaskets or indium wires provide a vacuum-tight seal to the cryostat. Windows with a wedge of 1° and 3° are used in laser engineering as partially...

Wear resistance Sapphire Window As Fingerprint Recognition

Devices and their components applied in aviation and space industries, in chemi-cal processing, and in many other fields are simultaneously subjected to the action of aggressive media, radiation, high temperatures, pressures, and mechanical loads. Under such extreme conditions any material is prone to intense...

Sturdy Sapphire Window As Fingerprint Recognition

Large-size sapphire crystals are needed for optics and airborne windows with apertures of 600 mm and larger (for the medium-wave IR region of the spec-trum). At present, the only material used for the windows with a diameter greater than 300 mm is ZnSe. Its ultimate strength reaches 69 MPa (10,000 psi). Large-size...

Transparent Sapphire Window As Fingerprint Recognition

The strength of a “glass sandwich” with a thickness of 25–35 mm will correspond to that of ~100-mm-thick armored glass. The upper layer of such a “glass sandwich” would contain a sapphire sheet meant to absorb the greater part of the kinetic energy of bullets. The rest of this energy will be absorbed in the layers of...

High hardness of Sapphire Window As Fingerprint Recognition

In contrast to ZnSe windows, those made of sapphire may have a thickness around 5 mm with a complete absence of optical scattering. As shown by recent investiga-tions, large area (500 × 500 mm and 1,000 × 1,000 mm) is necessary for making transparent armor used for the windows of helicopters, special-purpose vehicles....

Sapphire Window As Fingerprint Recognition

Sapphire meniscuses (domes) shaped as hemispheres are used for making the heads of IR-radiation guided missiles. Here, sapphire is employed due to the com-bination of its sufficient transmission in the region of 3–5 m m and its mechanical strength. The temperature of the working article, and consequently the value of...

Color Sapphire Window As Fingerprint

Sapphire energy withdrawal windows can be used. One of the factors that limit the withdrawal of energy from devices is secondary electron resonance discharge in vacuum proportional to the secondary . sapphire compares favorably with other dielectrics in this characteristic. Sapphire lenses and prisms are used under...
