Anti-Reflection Coated Optical Sapphire Glass Window

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...

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...

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...

Big Optical Margin Sapphire Glass Window

Ni crystal(yellow sapphire or “oriental topaz”) can reversibly acquire a smoky hue depending on the annealing medium. The color of ruby becomes more intense with the transition of chromium of different valences into trivalent chromium. The sapphires with too dark a blue color can be brightened by heating until some...

The width of the solid solution region is almost temperature-independent. The comparison of the absorp-tion spectra of blue ennobled and natural sapphires testifies to the coin-cidence of the absorption band maxima for these two objects.Ennobled blue sapphires have a faint pinkish hue typical of natural sapphires from...

high quality Wearable Sapphire Window Device

Stones for devices made of sapphire and ruby are most reliable. Sapphire pivots produced commercially in large quantities serve as supports for the shafts of those mechanisms that must work continuously for tens of years (e.g., water and gas meters). Such pivots are either flat or supplied with conical craters of...
