Abstract
We present a method to provide absolute intensity calibration of a common low-resolution, wideband optical spectrometer. Terrestrial solar radiation is employed as the source of illumination, and the spectrometer output is compared to a solar spectral standard to determine its calibration. Over 3 days of observation, the procedure is demonstrated to yield reproducible results. Other evidence of calibration accuracy is presented.
