Abstract
In an instrument for measuring the energy of optical radiation, particularly laser radiation, a number of radiation absorbing plate-like foraminous elements are disposed in a tubular housing such that the radiation entering at one end of the housing is successively absorbed by the radiation absorbing elements which are heated thereby, and a fan disposed at the other end of the housing moves cooling air through the housing and through the radiation absorbing elements whereby the air is heated. From the temperature increase of the cooling air which is measured by a temperature measuring element, the energy of the optical radiation entering the housing is determined.
