Saint-Gobain is a global leader in producing Sapphire (Single Crystal Al2O3) sheets, tubes & rods, which have a variety of industrial uses. Its optical, electrical, chemical, mechanical, and nuclear properties make it an ideal material for hundreds of applications. Frequently it is the combination of two or more properties that make sapphire the only material available to solve complex engineering design problems. Saint-Gobain’s sapphire products can commonly be found in semiconductor wafer processing, industrial systems/tools, and even in medical applications.
Features and Benefits
GGG, SGGG and NGG are used to grow semiconductor crystal layers. This process is called Epitaxy and is used in nanotechnology and in semiconductor fabrication.
Garnets substrates are used as substrates for liquid epitaxy. The lattice parameter of our crystals is well controlled and the surface polishing finishing is of the highest quality allowing a perfect epitaxy
We can offer crystals with a large variety of composition with a very homogeneous and well controlled lattice parameter in large diameters up to 4’’. Crystals of large dimensions are also available for specific applications like cryogenic ones.
We have a large industrial capacity available and we can provide unique pieces as well as thousands of wafers.
The spectral analysis of X-rays emitted by a sample after irradiation is both a powerful qualitative and quantitative analytical technique. It is based on the following phenomenon: an atom relaxes after excitation by emitting X-ray radiations at specific wavelengths, which reveal the identity of the emitting species.
A monochromator is an optical device that transmits a mechanically selectable narrow band of wavelengths of light or other radiation chosen from a wider range of wavelengths available at the input.
Monochromators are used in many optical measuring instruments and in other applications where tunable monochromatic light is wanted.
The curved crystals are used in instruments such as microprobes, scanning electron microscopes, Synchrotrons, XFEL, Plasma Physics.
Saint-Gobain offers a wide range of X-Ray Monochromator Crystals; LiF, Quartz or SiO2, InSb, Si, Ge, PET, ADP, Beryl, TlAP, RbAP, KAP, CsAP
