AAC Technologies, a global leader in advanced consumer electronics components and modules, and Eulitha AG, a pioneer in high-throughput optical lithography, today announced at the SPIE AR/VR Conference that AAC will begin utilizing Eulitha’s lithography technology for the volume production of Augmented Reality (AR) waveguides. This represents a significant milestone in the industry’s pursuit of scalable and affordable AR waveguide manufacturing.

AR devices are widely expected to become a primary interface for ubiquitous access to information through small displays placed in the user’s field of view. These devices are especially effective for the seamless delivery of AI-generated information. Periodic nanostructures, often called diffractive optics, are patterned on glass plates (waveguides) to enable images to be projected to the user’s eye while maintaining a clear view of the surroundings. Eulitha’s proprietary optical lithography technology enables the high-fidelity printing of high-resolution periodic patterns required for these diffractive optics at a low cost. The technology is akin to the photolithography methods that serve as the backbone for semiconductor fabrication, leveraging the same established supply chains for photomasks, photoresists, and EDA tools.

Production using Eulitha’s technology is expected to be available at AAC’s manufacturing facilities within this year, marking an important step toward meeting the growing demand for next-generation AR devices.

Howard Tao, Head of the AR/VR Business Unit at AAC Technologies, said: “We have been collaborating with Eulitha to qualify their unique optical lithography technology for our production lines and have been impressed by the performance. We are enthusiastic about the potential of this adoption to boost our position in this competitive field, thanks to the high-quality and low-cost production enabled by Eulitha’s tools.”

Harun Solak, CEO of Eulitha AG, added: “The adoption of our technology by a leading manufacturer like AAC is a significant step in the recognition of the advantages we offer to our customers. We believe the high throughput and reliability enabled by optical lithography will address the scalability issues currently facing the AR industry. We look forward to continuing our collaboration with AAC Technologies to enable the production of leading AR devices for consumers worldwide.”

AAC Technologies brings deep expertise in optical components, modules, and system-level integration. Through in-house capabilities and partner integration, AAC offers fully functional composite AR display modules, including waveguides, light engines (LEA), electrochromics, push/pull lenses, and eye-tracking, to its global customers.

This collaboration highlights a shared commitment by AAC and Eulitha to accelerate the industrialization of AR waveguides and support the broader ecosystem as AR moves toward mass-market adoption.
