SCHOTT RealView® offers excellence in all technical details

Exceptional field of view

SCHOTT RealView® glass wafers give a wider field of view than any other AR device component available today, thanks to their very high refractive index.

Crisp, clear vision

Superb images are achieved by the SCHOTT RealView® wafers’ extremely low total thickness variation, which results in superior sharpness and contrast.

Light yet durable

It’s vital that wearable technology is comfortable to wear, and SCHOTT RealView® glass wafers are light, keeping device weight to a minimum, as well as being strong enough to endure frequent use.

Customized solutions

SCHOTT offers plenty of flexibility on finish and can apply anti-reflective coating to SCHOTT RealView® glass wafers that perfectly match customer needs.

How SCHOTT RealView® works 

The thrilling area of augmented reality is set to transform how we all receive information, whether that’s at home, in the office, or simply walking around a town or city. Glasses equipped with SCHOTT RealView® glass wafers are able to insert content into a person’s view, giving them an extra layer of vision, one that offers information on anything from vital medical procedures to the latest football results.

This link between the digital and physical world is created by combining images from the real world with computer-generated content. This happens in four key stages:

  1. A projector emits the light waves of the digital image in the direction of the waveguides (SCHOTT RealView®).
  2. The projector‘s light waves are coupled into the waveguide at a defined position with the help of a grating.
  3. After guiding the light waves between the most perfect waveguide surfaces by total internal reflection, the light is outcoupled in another grating area and distributed towards the user. 
  4. The mobile, unfixed human eye perceives both the digital overlay and the real image behind the glasses. This creates the impression of augmented reality.
