The Department of Defense, specifically the U.S. Army Contracting Command-Redstone, is seeking information from potential sources to procure one LED-based Pico Solar Simulator. This simulator must meet stringent technical specifications, including a wavelength range of 350-1500 nm, an AM1.5G spectral mismatch of less than 5%, and spatial non-uniformity below 2% over a 25 mm by 25 mm area, along with high temporal stability and variable intensity control. The equipment is crucial for testing photosensitive materials, solar cell testing, and material degradation studies, enhancing the Army's operational capabilities. Interested parties are encouraged to submit white papers by April 7, 2025, detailing their offerings, with all submissions becoming government property.
