Abstract

This paper presents possibilities for higher precision in photometric laboratories in the daily calibration work. Since a number of national laboratories verify the basic quantity, the candela, by the use of a lamp, geometrical errors in the setup are often made. This increases the error of reproducibility. A simple, but special setup using a standard lamp - lampholder - mirror unit together with a laser system, is introduced. This system is also useful for adjusting and calibrating Goniophotometers as well as for the work on photometer benches.
