Technical Information

MIROGARD®  anti-reflective glass  also protects paintings, graphics and prints from the destructive effects of UV radiation. 48% of the UV radiation in wavelengths from 300 to 380 nanometers is absorbed and reflected. This means MIROGARD®  anti-reflective glass  already offers better protection than other art glazing products, even in its standard version.


Coating durability
SCHOTT invests a great deal of effort to ensure that art lovers the world over are not distracted by the glazing. MIROGARD® anti-reflective glass is dip-coated using the sol-gel process. The coating production process takes place under clean room conditions. Multiple titanium dioxide and silicon dioxide layers are applied one after another with nanometer accuracy and then burned in. The result is a high-tech, anti-reflective art glass of the highest quality with a surface that is extremely stable, easy to clean and highly resistant to abrasion.

All product benefits have been tested and passed the following tests:
  • copper chloride acetic acid spray test
  • sliding abrasion with Taber Abraser process
  • adhesive tape test
  • alcohol rubbing test
  • stylus test
