ABSTRACT
Visible and near infrared radiation power outputs are measured in the following manner. Firstly, in the visible region ,the discharge lamp is lit in the integrating sphere, as in the case of standard illumination lamps, thereby measuring the power( W) of radiation of each wavelength in the visible region. Subsequently , the relative radiation power between 200-2000nm is measured by spectroscopy .As a result of these two measurements , the power (W) of radiation of each wavelength (1nm interval) in the range of 200-2000nm is obtained.
