SCHOTT CONTURAN^® - anti-reflective glass for displays

At a Glance

CONTURAN^® is used whenever protection of precious displays in combination with minimized undesirable reflection is needed.

CONTURAN^® is an anti-reflective glass with an optical interference coating on either one or both sides. As a result, this coating design prevents optical reflections from sunlight or artificial light being caused by the glass surface.

CONTURAN^® can be used for different applications, including indicator board covers, railroad destination indicators, anti-reflective filters for technical displays, and many more. It can basically be put to use anywhere irritating reflections occur.

Technical Information

These anti-reflective characteristics are made possible by the sol-gel dipping process developed by SCHOTT. The glass is dipped in different metal oxide solutions.

Once dipped, the metal oxide coating layers are burned in at 450° C to 500° C. The oxidic layers produce interference that actually helps prevent annoying reflections. These layers are actually much purer and especially mechanically and chemically more stable than those processed with conventional PVD techniques (such as vapor deposition or sputtering, for example).

Pristine view of any display

every glass surface of uncoated glass reflects about 4% of light (8% overall both sides)
CONTURAN^® is covered on one or both sides of the float glass with multiple layers of metal oxides
anti-reflective layers can reduce reflection by 90%.

CONTURAN^® has less than 0.5% reflection on each surface and guarentees an unrestricted view due to high light transmission.
