High-Vacuum Compatible Sample Positioning Stages

The contract seeks a high-vacuum compatible rotary stage system under a total small business set-aside, with the NAICS code 334516 and a size standard of 1,000 employees, targeting small business contractors capable of delivering precision motion control equipment for use in NIST’s Gaithersburg, Maryland laboratory. The scope includes a large-aperture rotary stage with a 135–200 mm clear aperture, ±180° rotational range, ≤0.003° repeatability, and ≤0.004° accuracy, integrated with a motion controller compatible with Windows and LabVIEW, a DN100 CF vacuum feedthrough with electrical connections, and pre-manufacturing engineering services to ensure design alignment with NIST’s requirements. Optional deliverables allow for upgrades to achieve base pressures below 10⁻⁸ Torr or 10⁻⁹ Torr, with all items required to be new, unused, and delivered in original manufacturer packaging under F.O.B. Destination terms. The contractor must submit CAD drawings for approval prior to manufacturing and complete delivery within 18 weeks of design acceptance, with all components cleaned and bagged for high-vacuum service to prevent contamination. Evaluation favors technical capability above all, requiring non-prototype, non-refurbished equipment and documentation on vacuum-compatible materials and greases, followed by past performance in quality, timeliness, and communication, with price considered only after non-price factors are substantially equal. The firm-fixed-price contract mandates compliance with multiple FAR clauses, including Buy American, prohibitions on covered telecommunications equipment from restricted countries, affirmative action for workers with disabilities, anti-trafficking measures, and cybersecurity standards aligned with NIST SP 800-171 and FISMA. Offerors must register in SAM.gov, provide a UEI and CAGE code, and certify small business status, while also disclosing any conflicts of interest, affiliations with prohibited entities, or deviations in labor or supply chain practices. Proposals must be submitted electronically in four clearly labeled volumes—Technical, Past Performance, Price, and Terms and Conditions—with the latter limited to one page per past performance example. All submissions are due by 12:00 PM Eastern Time on June 5, 2026, to designated NIST email addresses, and invoices must be processed through the Treasury’s IPP system, not WAWF. The delivery and acceptance point is NIST’s Shipping and Re
