The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is conducting market research through a Sources Sought Notice for a Fast Steering Mirror System. This procurement aims to identify potential sources capable of providing a two-axis, high bandwidth, high resolution fast steering mirror system, which is essential for scanning confocal photoluminescence microscopy of quantum emitters in nanophotonic structures. The system must meet stringent technical specifications, including a replaceable mirror, closed-loop motion control, and precise angular resolution, to support NIST's advanced measurement technologies. Interested vendors should respond by providing detailed information about their capabilities and products to the primary contact, Elizabeth Timberlake, at elizabeth.timberlake@nist.gov, by July 6, 2025, as this notice is for market research purposes and does not constitute a commitment to award a contract.
