Abstract

The paper presents the method and the apparatus used in the characterization of photodiodes--type DFR 01--produced in Romania which are used in the spectral range of 0.38 divided by 1 micrometers . Thirty photodiodes were picked from a representative group. This process took into consideration two parameters: the shunt resistance and the dark current, both of them measured in a thermostat control enclosure, for a photoconductive mode. The photodiodes from the first third of the list were tested and measured from: the linearity of the answering signal and from the spatial uniformity of the signal on the receiving surface point of view. It was determined the relative spectral responsivity of the photodiodes with a good linearity, using the methods of substitution and comparison: the methods used a responsivity standard internationally certificated.
