Optical Sapphire Lens Achromatic lens

Sapphire fibers are used for the creation of compositional materials; they rein-force metallic and ceramic composites. The main requirements imposed on the fibers are high strength and reasonable cost. The fibers grown for composites have a diameter of 0.4–0.7 mm. Their length varies within the limits of approximately...

Transparent Smooth Sapphire Lens

Use in Optics Harder than other commonly used blasting materials, aluminum oxide grains penetrate and cut even the hardest metals and sintered carbide. Approximately 50% lighter than metallic media, aluminum oxide has twice as many particles per pound. Fast cutting minimizes the damage to thin materials by eliminating...

Clear-sighted Sapphire Window As Phone Cover

Sapphire lenses and prisms are used under extreme conditions that glass analogs cannot withstand, or due to high refractive index characteristic of sapphire. Sapphire could be used as windows: 1.mobile phone screens; 2. lens; 3. fingerprint recognition; 4. Wearable equipment windows and so on, because of its unique...

High purity Sapphire Lens

Bicrystalline substrates are used for the creation of the Josephson transitions on high-temperature superconductor films. The tapes for the bicrystals are grown onto a bicrystalline seed. The orientation of the wide plane is the growth direction being. The bicrystalline angle is equal to 2 × 14°. The production of...

Clear sighted Sapphire Lens

Ball lenses are great tools for improving signal coupling between fibers, emitters, and detectors. Polished sapphire and ruby balls are used with D = 0.3–6.35 mm ± 2.54 m m and a sphericity to within 0.64mm. CD disks are fabricated of polycarbonate. In the near future sapphire disks will be developed for long-term...

High hardness of Sapphire Lens

In some cases it is easier to carry out temperature measurements by means of traditional thermocouples, but in aggressive medium these quickly break down. Thermocouple casings made of sapphire in the form of tubes with hermetically sealed bottoms provide reliable protection of metallic thermocouples from aggres-sive...

Transparent bright Sapphire Lens

Sapphire shells for lamps, absorption cells, and filters of atomic (rubidium) frequency standards raise the characteristics of the devices: they diminish the rela-tive frequency change corresponding with the time of work and atmospheric pres-sure, decrease power consumption, and increase the mean time between failure...

sapphire glass cylinder lens

X-ray interferometers of the Fabry-Perot type at first contained silicon crystals as X-ray grids. Then a need arose for crystals possessing higher stability in a wide range of temperatures and pressures, so for this purpose sapphire was chosen. It should be expected that the creation of such interferometers will lead...

Flat faced Sapphire Lens

Sapphire scintillators have the following advantages: emission in the red region of the spectrum (690–900 nm) rather high light output, low levels of afterglow (Table 1.2 ), and insignificant absorption of their own radiation (~0.15 cm −1 ). Due to the radiation resistance of the matrix, sapphire stability is greater...

Without a scratch Sapphire Lens

Use in Optics Luminophor screens based on doped sapphire have been developed for accelera. They are meant for the registration of intense beam parameters by means of digital TV facilities . In comparison with other materials, such screens provide higher light output. Their light output is linear up to 2 ⋅ 10 14...

Sapphire ingots LED Grade

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...

high quality Sapphire Lens

Sapphire becomes a promising material for tunable lasers if doped with elements possessing wide absorption bands and wide emission regions. The most interesting among such elements are Ti 3+ , Cu 2+ , V 3+ , Ni 2+ , Co 2+ , Co 3+ , and Mn 2+ . Concerning three-dimensional elements, the widest luminescence spectrum is...
