The indices of refraction of glass laser hosts may be varied between approximately 1.5 and 2.0, and both the temperature coefficient of n and the strain-optical coefficient may be tailored by altering the chemical composition. Glasses have lower thermal conductivities than the alumina or YAG, however, which imposes limitations on their use in ...
IDEMIA (formerly known as OT-Morpho) is a French multinational technology company headquartered in Courbevoie, France. It provides identity-related security services, and sells facial recognition and other biometric identification products and software to private companies and governments.
In condensed matter physics and materials science, an amorphous solid (or non-crystalline solid) is a solid that lacks the long-range order that is characteristic of a crystal. The terms " glass " and "glassy solid" are sometimes used synonymously with amorphous solid; however, these terms refer specifically to amorphous materials that undergo ...
Doped metal oxides for use as transparent conducting layers in photovoltaic devices are typically grown on a glass substrate. This glass substrate, apart from providing a support that the oxide can grow on, has the additional benefit of blocking most infrared wavelengths greater than 2 μm for most silicates, and converting it to heat in the glass layer.
Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.
1) Clear soda is better for you than dark soda - FALSE In reality, one of the only differences between clear and dark soft drinks is that the clear ones don't usually contain caffeine, but the ...
Binding of the glass in the frame, causing stresses to develop as the glass expands and contracts due to thermal changes or deflects due to wind. Glass expands and contracts with changes in temperature and deflects due to wind, so almost all modern glass is set on resilient blocks at the bottom and with space for expansion at the sides and top.
L-1 Identity Solutions was formed on August 29, 2006, from a merger of Viisage Technology, Inc. and Identix Incorporated. [2] It specializes in selling face recognition systems, electronic passports, [3] such as Fly Clear, [4] and other biometric technology to governments such as the United States and Saudi Arabia.
