SCHOTT CONTURAN ® – anti-reflective glass for displays

CONTURAN® – SCHOTT´s 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.

Summary:

  • reduction of irritating reflections down to 90%
  • high transmission (>98%) and increased contrast
  • high abrasion resistance and chemical stability of the anti-reflective coating extends its lifetime, makes it hardly vulnerable and easy to clean
  • appears to be invisible and neutral in color (high color rendering index), yet enables perfect viewing

SCHOTT CONTURAN ® – anti-reflective glass for displays is unique due to …

High transparency and less reflections …

  • appears to be invisible and neutral in color, yet enables perfect viewing
  • high transmission characteristics (> 98%)
  • less than 0.5% on each surface
  • increased contrast due to minimized reflection
  • good view of dimly lit items


Unsurpassed durability …

  • high abrasion resistance extends the lifetime in the application
  • high chemical stability means that CONTURAN® is hardly vulnerable and easy to clean
  • mechanical and chemical toughening causes incleased mechanical and chemical durabilty
  • in total ideal characteristics for use as protection cover

 

    Wide product range …

  • wide-ranging portfolio for specific applications and processing requirements
  • optimized coating design for thermal tempering and chemical toughening

    Processing …

  • available as bent glass
  • can be adapted to meet customer needs by applying UV or IR protection
  • optional DARO easy-to-clean coating available
  • only anti-reflective coating that can be chemically toughened for optimized process chain

Area of applications by SCHOTT Architecture:

Information displays

  • customized cover glasses for digital signage, transportation and outdoor displays with various dimensions and customized screen printing and optional anti-fingerprint coating (DARO)

Medical & Biotech

  • cover glass for displays, e.g. in medical technology

Retail applications

  • doors for cooling furniture or glasses for counters, as well in bent form available

Lighting applications

  • cover glass for lighting applications with high transmission and reduced reflections

Industrial control

  • touch applications, e.g. machine control
  • ruggedized displays

These special characteristics are made possible by the sol-gel dipping process developed by SCHOTT. The base substrate is dipped in different metal oxide solutions, which creates a multi-layered coating that is only a few nanometers thick. Once dipped, the metal oxide coating layers are burned in at 450°C to 500°C.

Interference-optical extinction reduses annoying reflections on the glass surface to a minimum. These coating layers and the curing temperature ensure a mechanically and chemically much more stable coating surfaces than with the conventional PVD techniques (such as vapor deposition or sputtering, for example).

Pristine view of any display

  • every glass surface of conventional float 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
  • CONTURAN® with an anti-reflective coating on both sides reduces reflections by 90%

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

Glass substrate types

  • soda-lime glass (floatglass)
  • low-iron, extra-clear soda-lime glass
  • grey soda-lime glass (greyglass)
  • BOROFLOAT®
  • aluminosilicate glass
