If no alternate sources are identified, the Government intends to issue a Sole Source Award to Gigahertz-Optik, Inc. (110 Haverhill Rd Bldg B-STE 205, Amesbury, MA 01913-2123 U.S.) under the authority of FAR 13.106-1(b). The North American Industry Classification System (NAICS) code for this acquisition is 334516. The NIST Physical Measurement Laboratory (PML) Sensor Science Division (SSD) is developing new transfer-standard spectroradiometers for disseminating the spectral irradiance scale realized at Synchrotron Ultraviolet Radiation Facility (SURF) transferred to deuterium lamps. These spectroradiometers are required to have dual sensors, one for its spectroradiometer and the other for its broadband radiometer. NIST has a need for a quantity of two dual-sensor spectroradiometers that meet or exceed the following draft minimum specifications: Two (2) spectroradiometers with a minimum spectral range from 180 nm to 450 nm and a bandpass no larger than 1 nm. Calibrated between 200 nm and 430 nm. Dual-sensor design: a thermoelectric cooled back-thinned CCD array detector with at least 2048 pixels and a silicon photodiode detector with a temperature-controlled radiometric filter. 16-bit analog to digital converter for the CCD array detector. Stray light: 0.02 % or lower, plus software stray-light correction. Input optic: on-housing irradiance probe (without using an optical fiber) with a cosine angular response quality index f2 no greater than 3 %. Compact, weather-proof, temperature stabilized housing with dimension no larger than 110 mm x 110 mm x 55 mm (Length x Width x Height). Built-in optical filter wheel with at least 2 positions Electronic shutter with the minimum integration time range from 2 microseconds to 60 seconds. Pre-aged components for stability over time. Hardware trigger input port Communication interfaces: USB, Ethernet, RS232, and RS485. Software requirements: LabVIEW support, bandpass correction support, raw data support. Include 1-year warranty NIST conducted market research from December 2024 to February 2025 by performing internet searches; searches of GSA, FPDS, Thomas Register, and DSBS; and speaking with various companies to determine what sources could meet NIST’s minimum requirements. The results of that market research revealed that only Gigahertz-Optik, Inc. (UEI: ZB94NEFQG8Y6) appears to be capable of meeting NIST’s requirements. HOW TO RESPOND TO THIS NOTICE In responding to this notice, please DO NOT PROVIDE PROPRIETARY INFORMATION. Please include only the following information, readable in either Microsoft Word 365, Microsoft Excel 365, or .pdf format, in the response. Submit the response by email to the Primary Point of Contact and, if specified, to the Secondary Point of Contact listed at the bottom of this notice as soon as possible, and preferably before the closing date and time of this notice. Provide the complete name of your company, address, name of contact for follow-up questions, their email, their phone number and, if your company has an active registration in https://sam.gov, your company’s Unique Entity ID (UEI). Details about what your company is capable of providing that meets or exceeds NIST’s minimum requirements. Whether your company is an authorized reseller of the product or service being cited and evidence of such authorization. Identify any aspects of the description of the requirements in the BACKGROUND section above that could be viewed as unduly restrictive or create unnecessary barriers that adversely affect your firm’s ability to fully participate in a procurement for such services and explain why. Please offer suggestions for how the requirements could be organized or structured to encourage the participation of small businesses. For the NAICS code Indicate whether your company is (a) a small business or (b) other than small business. See the Table of Small Business Size Standards and the associated .pdf download file for small business size standards and additional information. If you believe the NAICS code listed in this notice is not the best NAICS code for the type of product addressed in this notice, identify an alternative NAICS code that you believe would be more appropriate for the planned procurement. If your firm has existing Federal Supply Schedule contract(s) or other contracts for products or services against which the Department may be able to place orders, identify the contract number(s) and other relevant information. Describe your firm’s experience (as a prime, subcontractor, or consultant) providing the products or services described in Background section. Provide any other information that you believe would be valuable for the Government to know as part of its market research for this requirement. Please let us know if you would like to engage to get a better understanding of the requirement or need additional information about the Government’s requirement for the products or services described in the Background section. QUESTIONS REGARDING THIS NOTICE Questions regarding this notice may be submitted via email to the Primary Point of Contact and the Secondary Point of Contact listed in this notice. Questions should be submitted so that they are received 5 days prior to the close of this notice. Questions will be anonymized and answered via sources sought notice amendment following the question submission deadline. IMPORTANT NOTES The information received in response to this notice will be reviewed and considered so that the NIST may appropriately solicit for its requirements in the near future. This notice should not be construed as a commitment by the NIST to issue a solicitation or ultimately award a contract. This notice is not a request for a quotation. Responses will not be considered as proposals or quotations. No award will be made as a result of this notice. NIST is not responsible for any costs incurred by the respondents to this notice.
