This is a market research notice from NIST seeking information on commercial sources for a specific infrared optical spectrum analyzer (OSA). The required OSA must have continuous spectral coverage from 1 mm to 5.6 mm, a spectral resolution of 2 GHz or better, and a noise floor of -85 dBm or better, along with a detailed list of other technical features. The analyzer will be used to benchmark new metamaterial infrared sensors for illicit drug identification. The notice instructs interested companies to submit capability statements, including product specifications and commercial details, via email to the listed contacts as soon as possible. No budget, performance location, or specific procurement timelines are mentioned in this description.
