Application of standard detectors to other photometric and radiometric quantities
Radiometric references for optical radiation measurements

The use of the references described above will require the use of transfer instruments adapted to each quantity, and therefore very varied. This article will focus on calibration in direct relation to the primary references of transfer sources or detectors for the spectral and global quantities of luminance, illuminance and intensity. Applications to pyrometric measurements will also be presented. Spectral measurements are systematically energetic (expressed in watts and declined according to angular or spatial quantities), while global measurements will also refer to photometric units, candela, lumen and lux.
