SwRI Ultraviolet Reflectance Chamber (SWURC)


General Description The SwRI Ultraviolet Reflectance Chamber (SWURC) is a state of the art UV reflectometer chamber and data acquisition system that can measure the bidirectional reflectance from 115 to 180 nm over various reflectance angles. UV reflectance spectroscopy is a valuable tool for studying airless planetary surfaces. However, the lack of laboratory measurements of materials at far-UV wavelengths has limited the interpretation of remote sensing UV data from the Moon, asteroids, comets, etc. The SwURC provides laboratory-based vacuum UV reflectance measurements of water frost/ice, lunar soils, simulants, and analogs to support interpretation of UV mapping data from current UV [...]
