Single Element Achromatic Lens Technology

The Army is seeking the development of achromatic lens technologies to reduce the space and weight of optical systems. To address this Army need, Physical Optics Corporation (POC) proposes to develop a novel Single Element Achromatic Lens (SEAL) technology based on metamaterials, dielectric nanoantennas, and form birefringence. The novel use and arrangement of the dielectric nanoantennas allows for achromatic focusing. The SEAL uses a monolayer metamaterial, which is thin and ultralight. Its achromatic behavior allows for focusing over a broad band of light without additional color correction features. Additionally, the SEAL is highly configurable to offer the desired lens properties. The simple SEAL design allows for cost-effective fabrication using advanced nanoimprint lithography. In Phase I, POC will demonstrate SEAL feasibility by designing, simulating, fabricating, and testing a prototype. In Phase II, POC plans to further develop a fully operational SEAL by refining and optimizing the design, developing the complete manufacturing process for mass production, and conducting thorough evaluation of optical performance in comparison to conventional lenses. By the completion of Phase II, we will have a mature working prototype that meets all Army requirements.
