The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is seeking responses for the procurement of an automatically tunable ultraviolet (UV) to infrared (IR) laser system. This system is essential for the Primary Optical Watt Radiometer (POWR) lab, which serves as the Nation’s optical power reference, requiring a laser capable of continuous wavelength tuning from 190 nm to 2300 nm with a narrow spectral bandwidth of approximately 10 cm−1. The procurement aims to enhance the calibration of optical power standards using advanced laser technology, with a focus on new equipment only, as used or remanufactured items will not be considered. Interested parties should submit their responses, including company details and capabilities, to the primary contact, Joni L. Laster, at joni.laster@nist.gov, by November 18, 2024, to be considered for this opportunity.
