Absolute power meters of optical radiation for the state measurement standards of Ukraine

One of ways of a volume expansion and increase of measurement accuracy is the application of an absolute meter of optical power on the basis a gangway of the detector. We suppose to apply such meter of power separately for visible and to infra-red wavelength band. For this purpose we suppose to mount an input of an optical detector the changeable adapter permitting to include meter connectors of optical cables of different standards and their modifications. The characteristics of the dependence of an output signal of the photodiode from a wavelength of the received signal for different photosensing materials are shown.
