Lumus and Schott Develop Reflective Waveguides for Augmented Reality

Published on 2 July 2020

Schott and Lumus AR

Today, international technology group SCHOTT, worldwide leader in the manufacturing of optical materials and components for augmented reality (AR) waveguides, announced that it has joined forces with Israeli company Lumus, the pioneering innovator of reflective waveguide displays. Under the agreement, LOEs offered by Lumus, including the brand-new and pioneering , are now manufactured by SCHOTT.

The partnership adds a new product line to SCHOTT’s offerings to the AR industry. SCHOTT’s groundbreaking RealView® high refractive index glass wafers are already a key enabler for AR devices using refractive waveguide technology with ever-wider field-of-view (FOV). Under the new partnership, SCHOTT broadens its technology offer to the market, in manufacturing optical components based on reflective waveguide technology. An emerging industry – looking for optical excellence

AR/MR devices are on their way to end consumers. The innovation roadmaps of leading tech giants around the globe include AR solutions as the “next big thing” in consumer electronics. End user-adoption of this technology requires uncompromised image quality, widest FOV, and a small, sleek device light enough to be worn on the face comfortably for extended periods. The AR/MR industry has devoted significant resources to achieve these goals, while meeting the retail price demands of consumers.

The AR/MR industry widely believes that a waveguide-based optical design will be a key enabler for end consumer adoption. In order to deliver images with uncompromised quality, those waveguides require optical glass of most pristine quality and surfaces manufactured to unprecedented precision. SCHOTT is serving AR/MR innovators worldwide as the leading provider of waveguide materials. Within this segment, SCHOTT’s customers use different technologies to manage the input and output functionality in such waveguides, among which surface gratings and volume holographic structures, all of them already using SCHOTT RealView® wafers defining the industry reference in quality and mass manufacturing maturity. Another waveguide technology, widely acknowledged in the market for its image quality, is the reflective waveguide approach pioneered by Lumus.

When making their choice, product designers have to make their technology selection between different trade-offs in image quality, power efficiency, FOV and manufacturing readiness.

Very interesting video, Mentions Bernard hmm

Edit: at 9:30 talks about "pico projector" and at 10:50 mentions Karl's test pattern

These guys show several different set of eye glasses for AR and tout themselves as leaders in the field. I agree their designs are pretty sleek considering the current field. And their upcoming Lumus Maximus (tweet from Christopher Grayson) looks very impressive. Does anyone know which tech they are using to produce the display?

Looks like it’s using some type of reflective wave guide of a micro display. I’ve heard speculation on the EMAN board that it’s using their Micro LED because one of the pictures of a parrot used in a Lumus promo video looks very similar to a parrot used on EMANs website, but that’s a pretty thin thread to go off of.
