Product Variants of SCHOTT RealView®
SCHOTT RealView® 2.0 lightweight
CHARACTERISTICS
SCHOTT RealView® 2.0 lightweight is an advanced optical glass wafer engineered for augmented reality waveguides. It combines a refractive index of 2.0 with a significantly reduced density compared to conventional high-index glasses, helping device manufacturers achieve thinner, lighter, and more comfortable AR wearables. High optical transmission and improved mechanical properties support superior image quality and long-term durability in demanding applications.
YOUR ADVANTAGES
- High refractive index of 2.0 for enabling larger field of view (FoV) designs.
- Reduced density for lighter waveguides and improved all-day wearing comfort.
- Excellent optical transmission for bright, immersive AR experiences.
- Advanced optical glass composition combining lightweight design with strong mechanical performance.
- Enhanced hardness and fracture toughness for improved durability and handling robustness.
- Proven suitability for precision wafer manufacturing and industrial-scale production.
- Available in large-format wafers to support next-generation AR manufacturing platforms.
- Built on SCHOTT's proven AR production track record with more than 500,000 wafers shipped worldwide.
SCHOTT RealView® ultra
CHARACTERISTICS
Decreasing glass density or wafer thickness can offer essential weight reduction for waveguides, but it comes at a price in terms of lower image quality. SCHOTT RealView® ultra not only improves wafer flatness by up to 60% but also boosts image quality, enabling AR device makers to minimize image variation between individual eye pieces and maximize production yields.
Applicable to the whole SCHOTT RealView® portfolio, this new ultra grade can also remove up to 30% of weight from the scale, and combined with the low-density SCHOTT RealView® 1.9 lightweight, SCHOTT RealView® ultra can even deliver a waveguide weight reduction of up to 50%.
YOUR ADVANTAGES
- Tight flatness control minimizes light beam deflections in the waveguides to enable the highest image quality.
- Higher tolerances for stacking multi-layer waveguides help increase manufacturing yield.
- Thinner lightweight waveguides can be produced without compromising image quality.
- Full immersive experience with the highest wearing comfort.
SCHOTT RealView® with titanium dioxide coatings
CHARACTERISTICS
With a broad variety of refractive indices, SCHOTT RealView® is the leading substrate for the additive method, with index-matching resins and a subtractive approach with direct etching into the glass.
To complement SCHOTT’s portfolio for the surface relief gratings industry, SCHOTT RealView® substrates are also available with dedicated coatings for reactive ion etching (RIE) applications. In combination with high-index RealView® substrates, this opens the door for the development of highly immersive devices with large Fields of View. By using a single high-performance waveguide layer, miniaturization and weight reduction can be taken to the next level.
YOUR ADVANTAGES
- Tight thickness control of TiO2 layer (nanometer range).
- High homogeneity in pinhole-free TiO2 layer.
- 'SCHOTT RealView® ultra' quality as the foundation for great performance.
- Tight roughness control.
- Strong adhesion between coating and wafer.
