Architectural glass

Optically Functional. Laser optics, layer architectural glass panels (up to 3 x 4.3 m), lenses, TV-camera optical elements, and similar apphcations require optically functional coatings. 

Architectural Glass. The other important commercial glass-platiag appHcation is for production of architectural reflective glasses. Translucent metal films are used for decoration and for reduction of environmental heat gain. Electroless plating is used by one producer for this type of product (48). 

Passivation layers in energy-saving architectural glass (E-glass). 

Deposition has been carried out on architectural glass yielding single-junction amorphous silicon with an efficiency of 13% in the laboratory, but with lower efficiency in production devices. An atmospheric-pressure deposition system in shown in Fig. 15.5. The gas injection device is shown in Fig. 15.6. 

Most AR coatings are still produced by evaporation but CVD is gradually introduced particularly in applications with three-dimensional surfaces or deep recesses. AR coatings are used in numerous applications, which include lasers, lenses for cameras and binoculars, instrument panels, microscopes, telescopes, range finders, etc., as well as on automotive and architectural glasses.

Polymer-dispersed liquid crystals are the next generation of display materials. Initial research has outlined the basic principles of their operation The PDLC films combine the properties of plastics and liquid crystals producing display devices impossible with conventional materials. They wfil be used in applications ranging from architectural glass to projection TV and optical computing. 

Use For fired-on labels and decorations on glassware, tumblers, milk bottles, beverage bottles, glass containers, illuminating ware, architectural glass, and signs. 

Indium-tin oxide (ITO) is indium oxide doped with tin oxide. Thin films of ITO have commercially valuable properties it is transparent, electrically conducting and reflects IR radiation. Applications of ITO are varied. It is used as a coating material for flat-panel computer displays, for coating architectural glass panels, and in electrochromic devices. Coating motor vehicle and aircraft windscreens and motor vehicle rear windows allows them to be electrically heated for de-icing...
