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
