Multiwavelength Tunable Stable Optical Cavity System

The National Institute of Standards and Technology (NIST), under the Department of Commerce, is seeking a Multiwavelength Tunable Stable Optical Cavity System through a Request for Quotation (RFQ) with solicitation number NB688000-26-01482. The system is intended to support the development of a chip-scaled voltage reference using Rydberg atoms and must meet stringent technical specifications, including a finesse greater than 10,000 at wavelengths of 852 nm, 510 nm, 638 nm, and 656 nm, precise zero-crossing temperature characterization and control, and a vacuum housing that encloses both the cavity and an ion pump. Only one unit is required, and all items must be new—prototypes, demonstration models, used, or refurbished systems are explicitly disqualified. The contract requires delivery, installation, and training to be completed within 18 weeks after receipt of order, with performance located in Boulder, Colorado. All submissions must be emailed to [email hidden], and every communication must include the solicitation number. The response deadline is June 26, 2026, and the procurement is classified under NAICS code 334516. While the government will conduct acceptance testing within seven business days, details regarding packaging, invoicing, payment terms, evaluation factors, and special contract requirements such as government-furnished material or travel are not specified in the documentation. The contract type and total value are also not provided.
