Iowa Patent of the Month – April 2025
DigiLens Inc., in collaboration with Rockwell Collins, Inc., has secured U.S. Patent No. 12,276,895 for a novel transparent waveguide display. Titled “Transparent waveguide display with passive expander input Bragg gratings with different angular diffraction efficiencies,” this innovation promises significant advancements in augmented reality (AR) and head-up display (HUD) technologies.
Enhancing Visual Clarity and Efficiency
The patented technology introduces a dual-layer waveguide system, each embedded with specialized Bragg gratings. These gratings are designed to manage light propagation in distinct directions, optimizing image clarity and brightness. By employing gratings with varying angular diffraction efficiencies, the system ensures precise light extraction, enhancing the viewer’s experience without compromising transparency.
Real-World Applications and Impact
This advancement holds promise for a range of applications, from AR glasses to automotive HUDs. By improving light management within transparent displays, devices can offer clearer visuals while maintaining a sleek form factor. Such enhancements are crucial for the seamless integration of AR technologies into daily life, potentially transforming how users interact with digital information in real-world settings.
DigiLens’s latest patent underscores its commitment to pioneering optical solutions that bridge the gap between digital and physical realms. As AR continues to evolve, innovations like this are pivotal in shaping the future of immersive technologies.

What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
