Glossary
ARAS is one of the most effective anti-reflection/anti-static screen treatments currently available. It
is composed of a multi-layer structure of transparent dielectric material that suppresses specular
reflections by broadband interference effects at the screen surface. Anti-static properties are
provided by a single conductive layer within the multi-layer structure.
With ARAS, the intensity of reflected light is reduced from around 4.5% of the incident light (the
reflectivity of uncoated screens) to less than 0.5%. ARAS also has a major advantage over other
screen treatments: It doesn't diffuse or scatter reflected light, so picture contrast and sharpness
remain completely unimpaired. It's also easy to clean and tough enough to withstand commercially
available cleaning agents.
The ARAS coating reflects only about 0.5% of the incident light.
AGRAS (Anti-Glare anti-Reflection Anti-Static) coating.
A combined anti-reflection, anti-glare, anti-static coating.
