SPATIAL UNIFORMITY OF THE SILICON PHOTODIODES FOR ESTABLISHMENT OF SPECTRAL RESPONSIVITY SCALE
Luciana Alves, Fabiana Reis, Miguel Torres, Giovanna Almeida, Iakyra Couceiro
Abstract:
The establishment of the absolute spectral responsivity scale traceable to the cryogenic radiometer depends on well-characterized optical detectors as radiometric scale transfer standards. The photodiodes used for the construction of such transfer standards need to be characterized in terms of spatial uniformity, spectral responsivity, shunt resistance and linearity. The spatial uniformity of a batch of Hamamatsu S1337-11 photodiodes was performed with a monochromatic beam in the spectral responsivity measurement facility with a X-Y translation stage. The spectral responsivity of such photodiodes had also been measured.
