Transmission Increase

More light, more performance thanks to TE surfaces.

Glass surfaces are optically changed by a specially developed surface treatment. A reduction in the index of refraction results in an increase in light transmission.

BG-TE etching can be performed on a host of glass types and geometries. For example, the transmission of highly curved lenses, glass moldings or tubes (also the inside of curved tubes) can be improved. With this process it is also possible to apply an anti-reflective coating to thermally strengthened safety glass after final treatment. This very cost effective method of producing anti-reflection surfaces reduces the residual reflection to roughly 1%.

A maximum yield of brightness and energy is the objective of functional glass in lighting applications, photovoltaics or solar collectors. The special surface treatment of our BG-TE glass substantially increases the proportion of the transmitted light.
