Product Variants of SCHOTT RealView®
SCHOTT RealView® 1.9 lightweight
CHARACTERISTICS
With a reduced density of 20%, SCHOTT RealView® 1.9 lightweight does not compromise in image quality and keeps the high refractive index, which is needed for the augmented reality industry.
YOUR ADVANTAGES
- High refractive index and low density offered at the same time.
- Proven suitability for nanoimprint lithography manufacturing.
- Index-matching resin available.
- Tailored for high mechanical robustness.
- AR industry track record in mass production of wafers consistently fulfilling the highest quality standards.
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.
