The National Institute of Standards and Technology (NIST) is conducting market research to identify sources capable of providing three high-precision rotation stages with a resolution better than 0.00005 degrees, a clear aperture of at least 80 mm, and a mass under 1 kg, along with control hardware and software. These stages are needed for a neutron interferometer requiring full 360-degree rotation, zero backlash, and the ability to maintain position during power loss, with two stages separated up to 0.3 meters and a third up to 5 meters. The location for performance is at NIST, with cables of 10 meters required to place the control box outside a radiation area. No budget amount or submission timeline is specified in this sources sought notice. Respondents must provide company details, product specifications, and capability information by email to the listed contacts.
