High-Stability Optical Reference Cavity Design and Fabrication

The contract calls for the design, manufacture, and integration of a vacuum-compatible, high-stability optical reference cavity intended for use in precision laser spectroscopy applications. The cavity must meet stringent stability requirements to ensure accurate and repeatable measurements under controlled vacuum conditions, and it must include a dedicated mounting solution for an ion pump to maintain the required vacuum environment. The system is expected to exhibit minimal thermal and mechanical drift, with materials and construction techniques selected to ensure long-term performance in a high-precision scientific setting. All components must be compatible with ultra-high vacuum standards and capable of withstanding the operational demands of laboratory-grade spectroscopy equipment. The work is scoped as a subcontract under the National Institute of Standards and Technology, part of the Department of Commerce, with performance based in Boulder, Colorado, at the 80305 ZIP code. The solicitation was posted on May 8, 2026, and responses are due by May 18, 2026, at 11:00 PM Eastern Time. The North American Industry Classification System code 334511 indicates the work falls under the manufacturing of instruments and related products for measuring and testing. This effort supports advanced scientific instrumentation initiatives and requires expertise in precision optical engineering, vacuum system integration, and metrology-grade fabrication methods.
