High purity Sapphire Window As Fingerprint Recognition
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. Sapphire could be used as windows: 1.mobile phone screens; 2. lens; 3. fingerprint...
2 inch 4 inch 6 inch Sapphire ingot
Historically, the crystals meant for laser elements were obtained by the Verneuil method. In the present day, the crystals employed for this purpose are grown from the melt by the Czochralski, Kyropoulos, and HEM methods and possess the high-est optical homogeneity . The growth media used in the crystal growth...
A zone scheme of an interactive system of traps has been proposed in the crystal, which includes a TL-active trap, a luminescence center, and a deep trap. One of the mechanisms responsible for the dose-characteristic linearity is the interactive coupling of the dosimetric and deep traps. Practical recommendations are...
6inch High hardness sapphire crystal bar
The crystals grown in the strongly reducing medium mentioned above have a high density of F and F + centers, the ratio of which may vary from one sample to another. The neutral F centers are characterized by 6.05 eV absorption bands; those positively charged possess 4.8 and 5.4 eV bands. Ingot Sapphire is the main...
100kg High hardness sapphire ingot
The upper boundary of crystal dimensions corresponds to the case when the photore-ceiver is connected to the crystal face perpendicular to incident radiation; it is calculated for the condition when the light from the most distant point exceeds the discrimination threshold (10 keV). the upper boundary for different...
120kg Corrosion resistant sapphire ingot
In the near future sapphire, as with silicon and germanium, will become one of the strategic materials for materials science. The main trends in the development of the sapphire industry will be the increase in the size of the grown crystals and the creation of technologies for obtaining permanent sapphire joints....
The growth of large-size sapphire crystals is an urgent problem. Required for this purpose are large crystallization units that provide not only high perfection of the crystals, but also quantity production. The use of such units essentially decreases consumption of both energy and materials, so the cost of the...
studied material and a thin ruby plate are clamped between sapphire plates. Under the influence of electric current or laser heating on the investigated plate, a pressure of ~100 kbar arises during 1–2 ms. The pressure is measured from the shift in the ruby luminescence peak value. A pulse at l = 532 nm is applied to...
top quality Sapphire Window As Fingerprint
Sapphire of different quality is employed in optical articles Sapphire windows with diameters from several millimeters to several hundreds of millimeters are applied in various devices that work on the ground, under water, and in outer space in a wide range of pressures and temperatures – from cryogenic to high...

120kg High quality sapphire ingot
Focusing cones (focones) also belong to light guide facilities. By means of sapphire focones the emission of high-power xenon lamps is transformed into a point or linear source (“light knife”). For the latter transformation the shape of the input face is calculated, allowing redistribution of incident light flux in...
120kg Bubble process sapphire ingot
The upper boundary of crystal dimensions corresponds to the case when the photore-ceiver is connected to the crystal face perpendicular to incident radiation; it is calculated for the condition when the light from the most distant point exceeds the discrimination threshold (10 keV). The upper boundary for different...
