SCHOTT CONTURAN® - anti-reflective glass for technical applications


At a Glance

CONTURAN® - SCHOTT´s interference optically anti-reflective coated glass enables perfect transmission in many technical applications with an almost reflection-free glass surface.

CONTURAN® is an anti-reflective glass with an optical interference coating on either one or both sides. SCHOTT developed a coating design that prevents optical reflections that result at the glass air passage. CONTURAN® enables almost invisible protection for many applications with the same highest light transmission and a high color rendering index combined with long durability and suitability for daily use.

CONTURAN® can be used for different applications, including cover glasses for indicator boards and technical displays for medical and industrial applications, doors for food displays, protective cover glasses for lighting applications 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.

Glass substrate types
  • float glass
  • low-iron, extra-clear glass
  • grey glass
