Abstract

In this paper methods of a spatial correction of a luxmeter photometric head are presented. It was found that a transparent element may be used in a luxmeter photometric head for its spatial correction. Furthermore the luminous efficiency of this type of photometric head is 4.3 times higher than that of photometric head used at present. Thus high photometric efficiency of this kind of the photometric head enables measurement of very low illuminance.
