High quality customized shape sapphire window

The watch industry was historically the first application field for artificial corun-dum crystals. As far back as 1704, Debraute and Fatio, mathematicians from Geneva, proposed to use gems in watch mechanisms, but this idea was economi-cally unfeasible at that time. As soon as ruby had been put into industrial...

Wear resistance of Sapphire Window As Phone Cover

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...
