Abstract

PURPOSE:To obtain high accuracy, by storing the spectral sensitivity characteristic data of a quantum type optoelectronic transducer and variation characteristic data of quantum efficiency with respect to a wavelength when a reverse bias voltage is imparted to the quantum type optoelectronic transducer beforehand. CONSTITUTION:The known spectral sensitivity characteristic data of a quantum type optoelectronic transducer 7 are stored in a memory 6 beforehand. The known variation characteristic data of quantum efficiency with respect to a wavelength when a reverse bias voltage is imparted to the element 7 are stored in a memory 9 beforehand. The memories 6 and 9 are provided in this measuring device. The memories are connected to an operation control part 8. A reverse bias circuit 10 is connected to the element 7. The output of the element 7 is connected to the control part 8. The wavelength of light to be measured (a) is obtained based on the variation in quantum efficiency when the characteristic data are given to the control part 8 and the reverse bias voltage is given to the element 7. The measured value of the element 7 is automatically corrected based on the measured wavelength and the spectral sensitivity characteristic of the memory 6.
