Nano-Scaffolding Assembly of Materials for Next Generation Uncooled Thermal Optics

Irradiant Technologies is poised to revolutionize uncooled long wave infrared (LWIR) thermal imaging sensors, vital for the Army’s needs in night and obscured condition operations. These sensors, integrated into soldiers' gear and drones, are essential for enhancing situational awareness and combat effectiveness on the modern battlefield. However, traditional optical components in these sensors have not advanced significantly in decades, struggling to meet the demands for lower size, weight, power, and cost (SWaP-C).Addressing these challenges, Irradiant introduces a groundbreaking nanoassembly approach to optical component design. Unlike conventional methods reliant on labor-intensive and costly single-point diamond turning, Irradiant employs a novel method using a porous scaffold with 3D lithographic patterning and click chemistry. This allows for the precise deposition and control of high-dielectric materials, creating optical components not by traditional shaping but through innovative dielectric mapping. This approach offers unprecedented control over light manipulation, enhancing the functionality of optical components while significantly reducing their size and complexity.The proposed technology leverages Gradient Index (GRIN) patterning capabilities far superior to existing methods, enabling high index contrast at scales unattainable by traditional fabrication techniques. With the capability to produce millions of components annually, our digital fabrication process drastically cuts R&D cycles and system costs, allowing for rapid deployment and scalability. Phase I of the project will focus on a comprehensive analysis of infrared-compatible materials like PbS and ZnSe, assessing their potential in MWIR and LWIR applications. This phase will also involve the design and modeling of a prototype thermal optical component to demonstrate the SWaP-C benefits of our platform. A Phase II effort would construct and test a prototype on an uncooled thermal camera test bed.
