title: Radiometer to monitor low levels of ultraviolet irradiance.
abstract: A scanning radiometer, using eight interference filters, has been developed at the Smithsonian Radiation Biology Laboratory for monitoring the spectral distribution of daylight. The unit has been designed to perform in the natural environment with a minimum of maintenance. The range of intensities it can cover is three to four decades, depending on the filtering and detectors.
