What is Anti-Reflective Glass?

Anti-reflective (A/R) glass is glass with single or multiple layer coatings, such as TiQ2, SiQ2. The purpose of these coatings is to reduce the reflected light from the surfaces of glass and/or increase the amount of light transmitted through the glass.

Anti-reflective coatings for a single wavelength may be easily designed using a single layer, usually magnesium fluoride in the visible range of the spectrum. As the range of desired wavelengths gets broader, multiple layers of differing materials are used. Ultraviolet wavelength and infrared wavelength performance may require more exotic layering and materials. A general rule is that as the desired wavelength range gets broader, the more complexity is required in the coating designs. Likewise, as the desired level of reflectivity reduction gets lower, or the desired improvement in transmission gets higher, the more layers and complexity is required in the coating designs.
