Abstract
To measure the angular response of radiometers developed in the laboratory, an automated system was assembled and characterized. The main light source is a QTH lamp of 1000W and for UV radiometers a Hg(Xe) lamp of 500W. The light beam has a useful diameter of 40 mm, a half divergence of 10mrad and the spatial uniformity is better than 97%. Errors up to 5% at large angles were estimated for misalignments of 1° in the positioning of the radiometers . In this work details of the system and results of measurements obtained with radiometers developed in the laboratory and with commercial ones are presented.
