Optical & Display Modules

Diffractive waveguides utilize nano-imprinted surface relief gratings (SRG) to manipulate light through internal reflection, allowing for an incredibly thin and lightweight profile ideal for sleek AI glasses. In contrast, reflective waveguides use a series of geometric semi-reflective mirrors embedded within the glass. While reflective types often provide superior color fidelity and higher contrast with less "rainbow effect," they are generally thicker and more challenging to integrate into standard, fashionable eyewear frames.

Yes, our optical modules are specifically designed with the end-user in mind. The waveguide substrates feature a slim form factor that leaves sufficient clearance for "magnetic clip-on" or "snap-in" prescription lens inserts. We also provide our partners with comprehensive mechanical reference designs for frames that can accommodate standard ophthalmic lenses positioned directly behind the AR waveguide, ensuring that AI smart glasses remain accessible to the billions of people who require vision correction.

Thermal management is a priority in our light engine design. We utilize high-thermal-conductivity ceramic substrates and lightweight magnesium alloy housings that act as passive heat sinks. Furthermore, our Micro-LED and Micro-OLED modules are optimized at the silicon level for ultra-low power consumption, which significantly reduces the thermal footprint. Combined with intelligent power-management firmware that adjusts brightness dynamically, our engines maintain a safe operating temperature even during continuous high-performance AR rendering.

The eye-box refers to the 3D volume in which the user's eye can perceive the full AR image without vignetting. Our standard waveguides offer a generous eye-box of approximately 12mm x 10mm. A larger eye-box is crucial because it accounts for different interpupillary distances (IPD) among users and ensures the digital overlay remains visible even when the glasses shift slightly during physical activities like walking, running, or working in industrial environments, greatly enhancing user comfort.

Our modules are specifically engineered for high-ambient readability. Our specialized Micro-LED engines can achieve brightness levels of up to 2 million nits at the light source, delivering over 5,000 nits to the eye after waveguide transmission—perfect for clear visibility in direct sunlight. For indoor use, the system integrates with ambient light sensors to provide dynamic dimming, allowing the display to scale down to comfortable levels, protecting the user's vision and significantly extending the device's battery life.
