Low-Temperature High-NA Objective Lens Supply

The contract seeks the supply of a specialized 50X apochromatic objective lens designed for operation at cryogenic temperatures of 4 K, with a numerical aperture exceeding 0.8 and a working distance greater than 0.6 millimeters, optimized for excitation at 532 nanometers. The lens must incorporate closed-loop piezo Z-positioning control to ensure precise and stable focal adjustments under extreme thermal conditions, critical for high-resolution imaging in low-temperature scientific applications. The component is intended for use in advanced research environments requiring exceptional optical performance and mechanical reliability at cryogenic temperatures. This subcontract, issued by the National Institute of Standards and Technology under the U.S. Department of Commerce, is posted with a response deadline of August 5, 2026, and falls under NAICS code 333291 for other commercial and industrial machinery manufacturing. The performance location is specified as Gaithersburg, Maryland, with a zip code of 20899. The solicitation is open to qualified vendors capable of delivering a custom optical system meeting stringent technical specifications, with no set-aside classification indicated. Potential bidders must respond prior to the deadline to be considered for award.
