The Department of Defense, specifically the Army branch, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program for the development of an apparatus and method to certify the properties of infrared optical materials. The primary objective is to create a cost-effective process for certifying the index of refraction of infrared materials, which is currently not performed on a batch basis, thereby ensuring the optical performance required for military applications. This initiative is critical as it addresses the need for precise certification of materials such as Germanium and ZnS, which are essential for infrared optics, and aims to transition the technology for in-line use at manufacturing points. Interested parties should note that the solicitation is currently closed, with the application due date having been October 1, 2024, and further details can be found at the provided source link: DOD SBIR.
