UV-Spectroradiometer with low-stray-light CCD
This set-up was developed for the measurement of the hemispherical ultraviolet irradiation in the spectral range from 280 nm to 480 nm. The excellent cosine characteristic provided by a special integrating sphere made of highly UV-reflecting and durable PTFE allows an easy handling and long calibration intervals. The accuracy basically depends on the calibration and is completely sufficient to substitute any integral UV-sensors.
