SPIE AR, VR, MR: The merits and challenges of world leading materials and waveguide substrates for AR/MR devices
9:00 PST / 12:00 EST / 18:00 CET

The advent of the AR industry is accompanied by large efforts at all participants of the value chain to create light management technologies fitting the wearable AR/MR devices and its use case.

Two major use cases are beginning to surface. One focuses on wearability, fashionability and all-day comfort. It also serves as a platform for communication and information type content. The second is dedicated to delivering maximum immersion, a wide field of view and crystal clear imaging representing the basis for gaming and enterprise type content. The technological side behind this comes with a conflicting set of requirements that need to be balanced carefully.

SCHOTT’s contribution to enabling the success of the AR industry lies in close collaboration with our partners and translating our deep technological understanding of the AR relevant parameters of the waveguide into world leading glass materials and waveguide substrates.

On the material end, we will guide you through SCHOTT’s world of material science and technology: linking atomistic structure of the glass and hence electron density creates refractive index, fracture toughness and its effects on robustness of a product, internal transmission and the impact of bandgap, impurities and their effect on the melting process. On the wafer end, we will take you to the opportunities and limits of drawn glasses as well as polished glass and its topological parameters affecting the waveguide performance. Additionally, we will show what a consumer scale market launch would mean from the perspective of a glass supplier based on our track record of a successful AR ramp up. To conclude, we will emphasize the importance of an efficient manufacturing ecosystem and SCHOTT’s effort to co-create this in order to turn the efforts undertaken by the industry into a bright future.

By signing up for this online event, I agree that SPIE may send me relevant communications via email.
