The U.S. Army seeks market research for the potential purchase of one high-performance Optical Spectrum Analyzer, equivalent to a Yokogawa AQ6370E-20 model, to replace aging equipment. The required item must meet specific technical specifications, including a wavelength range of 600 to 1700 nm and a wavelength accuracy of ±0.01 nm. The analyzer must be delivered to the Army Primary Standards Laboratory at Building 5435 Fowler Road on Redstone Arsenal, Alabama. This is a Request for Information to identify potential sources under NAICS Code 334515.
