AMIRAN®

AMIRAN® anti-reflective glass has a vast range of advantages over conventional float glass, offering negligible reflection, high light transmission and enviable durability. With a number of processing options, its qualities are extended further to produce one of our most versatile and popular glasses.

Strength, resilience and clarity

Powerful anti-reflection

AMIRAN® has excellent anti-reflective qualities thanks to SCHOTT’s pioneering sol-gel dipping process, which produces high levels of interference that generate just 1% reflection (compared to 8% with float glass).

Ultra-clear

This glass is incredibly clear, scoring a superb 100 on the color rendering index, and is highly receptive to light, allowing up to 98% of light rays to pass through.

Processing options

AMIRAN® offers a range of processing choices, with the option to bend the glass and its coatings for inspiring architectural designs.

Strong and hard-wearing

A strong protective coating makes AMIRAN® extremely robust against the damaging effects of harsh weather conditions. It also has high levels of chemical and scratch resistance.

Anti-reflective properties

AMIRAN® anti-reflective glass is a float glass with optical interference properties coated on one or both sides to minimize surface reflections. A special immersion procedure is used to apply multiple metal oxide layers just nanometers thick. Reflections are reduced optically by up to 90% and the glass appears invisible. At a transmission of > 98%, viewers can then focus on what’s important.

 

Advantages of SCHOTT AMIRAN®

  • Luminous reflectance of 0.9%
  • Appears invisible
  • Neutral in color
  • High transmission
  • Color rendering index of Ra = 100

 

Float vs. anti-reflective glass

Conventional float glass has dependable but limited optical properties. At just 91% transmission, a significant amount of light is lost. The smaller share of this (approximately 1%) is absorbed by the glass itself. The other 8% is reflected by the glass surface. This reflection is perceived as highly inconvenient, especially in applications which require clear viewing. Surface finishing can help here.

 

Disadvantages of float glass

  • Luminous reflectance of 8%
  • Undesirable reflections
  • Lower transmission
  • Colors appear drab
  • Displays art with unsophisticated colors

Tests and cleaning

SCHOTT invests a great deal of time and effort to ensure that art lovers around the world have an uninterrupted view of their favorite pieces. 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.

 

Benefits of SCHOTT dip-coated glass

  • Burned-in surface coating 
  • Highly resistant to abrasion 
  • Extremely stable

AMIRAN® is also mechanically robust and highly resistant to chemicals, delivering durable performance in every application. Key properties include:

  • High mechanical durability proven by international standards
  • Easy handling and processing
  • Robust surface for daily cleaning cycles

 

Testing

AMIRAN® undergoes a series of rigorous tests, split into mechanical and chemical:

 

Mechanical tests

  • The Tesa Test highlights the durability against the forces of adhesive tape being ripped from the coating.
  • Taber Abrasion Test, which tests the abrasion resistance of the coating.

  • The Pencil Hardness Test checks scratch resistance. Here AMIRAN® achieved class 9H, a significantly higher score than other anti-reflective surfaces.

  • The Cheesecloth Test is a good indicator of the resistance of the coating. It’s based on DIN ISO 9211-4 and simulates moderate abrasion. In this test, a cushion of gauze is pressed onto a coated surface with a certain force and then moved several times. The surface is then checked for damage. Competing products are 95% worse than SCHOTT products in this test.

Chemical tests

  • Standardized CASS (Copper-accelerated Acid Salt Spray) test
  • NSS (Neutral Salt Spray) test, which examines the anti-corrosive coating
