Near-infrared Photomultiplier Tube

The Department of Commerce National Institute of Standards and Technology issued solicitation NB687050-16-04498 for the procurement of one near-infrared photomultiplier tube to support greenhouse gas monitoring research within the Quantum Electromagnetics Division. The contract requires a device with an IR spectral sensitivity range of 1000 nm to 1700 nm and specific quantum efficiency thresholds of over 1.5 percent from 1000 nm to 1600 nm and over 0.15 percent from 1600 nm to 1650 nm. To ensure the detection of faint signals and heterodyne signals between 100 MHz and 300 MHz, the tube must maintain dark counts below 5000 counts per second, a dark current under 1 nA, and a time response of 3 ns. Additionally, the detector must have an effective diameter of at least 1.0 mm to accommodate the collection fiber. The procurement process follows a Lowest Price Technically Acceptable selection method, with quotations due by August 18, 2016. The successful contractor is required to deliver the equipment within 12 weeks after receipt of order. While the contracting office is located in Gaithersburg, Maryland, the place of performance is designated as Boulder, Colorado. This acquisition is categorized under NAICS code 334413 and is managed by the Department of Commerce.
