A hemispherical goniophotometer is disclosed, in which two pivoting arms are articulated on a revolving rotating arm and are each fitted with a measurement head. The geometry of the arrangement is chosen such that the measurement heads can move along the envelope surface of a hemisphere during rotating of the rotating arm through 360&#xb0; and pivoting of the pivoting arms through 180&#xb0;.
