NIST has issued a Request for Information/Sources Sought Notice (NB675030-26-000063) to gather information from industry regarding the availability and capability of businesses to provide a high-precision, laser-powered electric field probe. This notice is for market research to determine an acquisition strategy, not a solicitation. NIST anticipates delivery 90 days after order receipt. Interested parties are requested to submit responses by January 13, 2026, including company information, suggestions for specifications and evaluation factors, standard commercial pricing, experience and capability with similar probes, small business compliance with FAR clause 52.219-14, and details of any GSA or federal contracts. Responses should be in Microsoft Word or PDF format, 12-point font, and limited to four pages (excluding cover page and pricing).
The National Institute of Standards and Technology (NIST) requires a Laser-Powered Electric-Field Probe for accurate measurement and monitoring of electromagnetic field strength. This probe must operate within a frequency range of 9 kHz to 18 GHz and field strength ranges of < 1 V/m to >5 kV/m (9 kHz-1 GHz) and < 1 V/m to >1 kV/m (1 GHz-18 GHz). It must withstand damage thresholds of >25 kV/m (9 kHz-1 GHz) and >5 kV/m (1 GHz-18 GHz). Key specifications include a resolution of <= 0.05 V/m and measurement rates of at least 500 kSamples/s (continuous) and 2 MS/s (burst). The probe requires ISO 17025 accredited calibration with a certificate. Physical characteristics demand dimensions less than 46 x 46 x 114 mm3, a protective casing, and screw mounting. It must be powered and controlled via optical fiber, with 15-meter fiber optic cables supplied, featuring standard ST, FC, and/or FSMA connectors and a bending radius of >30 mm. The accompanying field meter must support simultaneous power and communication for at least five probes, apply separate calibration, and accept factory and user-defined calibration factors. Power can be 120 V AC or USB2/USB3. PC control via USB is required, with software for real-time data acquisition and display, licensed for indefinite NIST use. Delivery is required within 90 days, with a 3-year warranty covering labor, parts, and travel. Inspection and acceptance will occur on-site by NIST personnel.
