The Department of Defense (DoD) is seeking proposals for the development of a commercial single crystal growth process for 50mm diameter zinc selenide (ZnSe) wafers. The technology falls under the Directed Energy (DE) and Advanced Materials critical technology areas. The objective is to produce high-quality, optically clear ZnSe crystals for infrared countermeasure applications. The solicitation is looking for a scalable growth process and the delivery of ZnSe crystals with specific dimensions and orientations in each phase. The project duration and funding specifics are not mentioned in the document. Interested parties can find more information and submit proposals on the DoD SBIR website.
