Low Line Density Grating

The Department of Energy Office of Science, through Brookhaven Science Associates, LLC, is soliciting quotes for the design, fabrication, and delivery of a Low Line Density Grating for the National Synchrotron Light Source II (NSLS-II) Inelastic Scattering, Photoemission and Infrared Endstation (INSPIRE) beamline. The procurement requires a vendor to fabricate and test variable groove depth laminar grating rulings with specific technical requirements, including a single crystal silicon substrate, precise dimensional tolerances, groove profile specifications, and 30 nm gold coating. Offerors must demonstrate previous experience fabricating comparable grating rulings and provide references along with an acceptance test report demonstrating technical capabilities. The contract will be awarded to the lowest-priced, technically acceptable offeror who meets all technical requirements under a firm-fixed price structure. Questions are due by August 14, 2025, with quotations due by August 26, 2025 at 4:00 PM EDT, and vendors must be registered in the System for Award Management (SAM).

This procurement is conducted under full and open competition with no set-aside designation, classified under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing) with a size standard of 1,000 employees. The contract value is to be determined (TBD) and follows a milestone-based payment structure across five phases, with payment terms of Net 30 for large businesses and Net 10 for small businesses. The procurement involves delivery of a single soft X-ray Variable Groove Depth and Variable Line Spacing Laminar Grating with a 24-month delivery timeline after contract award, including specific milestones for manufacturing plans (2 weeks), acceptance test procedures (2 weeks), factory acceptance test reports (23 months), and final delivery (24 months). The place of performance is Upton, New York, and the contractor must provide a two-year warranty against failures and defects from final acceptance.
