Abstract:
An arrangement for measuring power or energy of optical radiation of radiation sources, especially laser radiation, having a housing comprising:a module defining at least one of an open and at least partially closed hollow space being provided, said module having inner and outer walls;at least one of the inner walls and outer walls of the module being at least one of entirely and partially occupied by detectors for generating measurement signals which are proportional to measured parameters of the radiation sources;said detectors being connected together in such a way that the generated measurement signals of said detectors are further processed to form at least one resultant sum signal;said at least one resultant sum signal being relatively independent from the position, arrangement and radiating characteristic of an examined radiation source in the module; andat least one of an opening and guide-through being provided in the module for inserting the radiation source to be examined.
