Customized Glass Sapphire Windows

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...

1mm High Quality Sapphire Optical Glass Windows

The light sources in which light-emitting diodes are used instead of filament lamps allow reduction of electric power consumption by approximately ten times. It has been calculated that the funds that could be saved due to the substitution of conven-tional light sources by light diodes in all the world’s lighting...

Irradiation with X-rays, cyclotron, reactor, and other kinds of radiation changes the valences of some impurities or favors intensification of the existing color cent-ers or formation of new ones. After irradiation, colorless and pink sapphires acquire orange color. There is no point in irradiating ruby, since this...
