120kg High hardness sapphire ingot

The crystals intended for use as TLD are grown in the form of calibrated rods by the Stepanov method in a strongly reducing medium. The rods are then cut into 1-mm-thick tablets with a diameter of 5 mm, after which their own background is measured. To make a set of detectors with a preset spread of sensitivity values,...

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...

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...

Transparent Smooth Wearable Sapphire Window Device

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,...

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...

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...

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...
