Precise measurement of photodiode spectral responses using the calorimetric method

The optical radiation from a monochrometer is used as a standard radiation source. The radiation power at each wavelength is determined by a highly sensitive and wavelength-independent calorimeter. The accuracy of measuring the spectral responses of various kinds of photodiodes is improved to better than 2% at any wavelength. Wavelength resolution of better than 16 nm is obtained.<
