Cellid Waveguide Light Guide for AR

Cellid Waveguide Light Guide is a technology designed for Smart Glass applications, showcased by Sher from Cellid at    • Display Week 2024   The waveguide serves as the lens component for smart glasses, comprising both glass and plastic variants. The glass waveguide offers a wide field of view (FOV) of F 60, while the plastic waveguide, though narrower at FOV 30, boasts an incredibly light weight of only 3 grams, making it noticeably lighter. Sher emphasizes the impressive performance efficiency of both versions, particularly highlighting the lightweight nature of the plastic variant.

This technology accommodates various projection methods, including DLP, LBS, micro LED, and laser R scanning, allowing flexibility in projector selection based on specific advantages and requirements. Despite acknowledging competitors in the waveguide market, Sher asserts the superiority of their product, emphasizing its quality and performance. With mass production slated to commence within a year, Sher anticipates significant quantities reaching the market, aiming to cater to a wide consumer base.

Optical quality is paramount in this technology, ensuring sharp and clear images to prevent discomfort or nausea for users. Sher underscores the importance of maintaining high image quality, which is integral to the design of the waveguide system. Addressing a query regarding the comparison between augmented reality (AR) and virtual reality (VR), Sher highlights the distinct nature of each technology, emphasizing their differing use cases. While VR is primarily for entertainment, AR focuses on real-world applications, aligning with Salet's current focus on enhancing everyday glasses with augmented capabilities.

Salet envisions integrating their waveguide technology into conventional glasses to achieve a transparent, lightweight design. The concept model presented illustrates the potential future direction of their product line. When discussing future developments, Sher mentions ongoing efforts to widen the field of view, with aspirations for FOV extending beyond 60 degrees, possibly reaching up to 90 or even 180 degrees. Salet, based in Tokyo, Japan, benefits from the rich knowledge base in optics within the country, drawing upon expertise from individuals with backgrounds in companies like Panasonic.

The company's origins in Japan highlight the cultural and technological influence shaping their innovations. Sher hints at the presence of skilled professionals with experience in optics and camera technology, suggesting a strong foundation for Salet's endeavors. As the conversation concludes, Sher invites further inquiries and contacts, positioning Salet as an accessible resource for those interested in their waveguide technology. Overall, the discussion elucidates Salet's vision for revolutionizing glasses with advanced optics, poised to make significant strides in the near future.
