THIS IS A COMBINED SOURCES SOUGHT NOTICE AND NOTICE OF INTENT TO SOLE SOURCE

Announcement Number: NIST-SS26-77

Subject: Notice of Intent to Noncompetitively Acquire AF UV spectroradiometer

This notice is not a request for a quotation. A solicitation document will not be issued, and quotations will not be requested.

This acquisition is being conducted under the authority of FAR 13.106-1(b) via FAR 13.106-1(b). The North American Industry Classification System (NAICS) code for this acquisition is 334516, Analytical Laboratory Instrument Manufacturing.

BACKGROUND

The semiconductor supply chain is global, specialized, and interconnected. Chipmakers do business with NIST is fulfilling a project with the Air Force (F4FTML5267G001) to characterize and calibrate a new transfer-standard spectroradiometer for disseminating the spectral irradiance scale realized at SURF transferred to deuterium lamps. These spectroradiometer are required to have dual sensors, one for its spectroradiometer and the other for its broadband radiometer.

The acquisition is for two dualsensor spectroradiometers with a back-thinned, cooled CCD array detector for its spectroradiometer and a photodiode for its temperature-controller radiometer.

NIST requires a spectroradiometer with the following capabilities: (1) a minimum spectral range from 190 nm to 430 nm and a bandpass no larger than 1 nm, and (2) dual-sensor design (a thermoelectric cooled back-thinned CCD array detector with at least 2048 pixels and a photodiode detector with a temperature-controlled radiometric filter).

It is critical to meet these requirements to have the capabilities to disseminate the spectral irradiance scale realized at SURF transferred to deuterium lamps at the lowest possible uncertainty for the Air Force. A bandpass

Multiple companies were found through market research that provide dual-sense spectroradiometers; however, only Gigahertz-Optik was capable of meeting all of NIST’s minimum requirements.

The minimum specifications regarding these items are listed below.

NIST conducted market research from December 2025 – February 2026 by conducting online searches, discussions with sources, and discussions with colleagues to determine what sources could meet NIST’s minimum requirements. The results of that market research revealed that Gigahertz-Optik, Inc., 110 Haverhill Rd Bldg B-STE 205, Amesbury, MA 01913-2123 United States, UEI: # ZB94NEFQG8Y6 appears to be capable of meeting NIST’s requirements.
