Special Notice: NATIONAL AERONAUTICS AND SPACE ADMINISTRATION is seeking inquiries from companies interested in obtaining license rights to commercialize, manufacture, and market a simplified hi-res flow visualization assembly. This assembly, developed by researchers at NASA's Langley Research Center, is a compact and easy-to-use optical system that enables focusing schlieren imaging. It reduces complexity and alignment time compared to conventional systems, and is self-aligned, compact, and cost-effective. The assembly can be attached to a commercial-off-the-shelf camera and is capable of fields-of-view of 10 and 300 millimeters. Interested parties can submit a license application through NASA's Automated Technology Licensing Application System (ATLAS). For more information, visit the NASA Technology Transfer Portal. No follow-on procurement is expected from this notice.
