Abstract:
A photoelectric detector device to be used in atomic absorption spectroscopy, characterized by:a photo semiconductor array having a plurality of photo semiconductor devices (A, B, C; A1, B1, C1; A2, B2, C2, A3, B3, C3), andread-out means (120; 220; 320, 420a, 420b) for reading out charges generated by impingement of radiation in the photo semiconductor devices, of any continuous portion in the photo semiconductor array, and for generating electric signals corresponding to the read-out charges, said readout means including plurality of inputs (121, 221) each coupled to a photo semiconductor device of the photo semiconductor array.an output (122, 222) for a signal from the input and which output corresponds to read-out charges from photo conductor devices,switching means (123, 223) interposed between the inputs and the output and connecting selected inputs to the output so as to deliver a signal representative of the combination of the selected inputs to the output, the switching means having at least one switch downstream from and associated with a plurality of the inputs to couple the associated inputs with the output of the read-out means.
