ABSTRACT:
The object of the present invention it to provide an optical spectrum calculation method that can find an optical spectrum by an arbitrarily determined wavelength bandwidth even in a spectrometer in which the width of the emission slit cannot be arbitrarily changed.
In order to attain this objective, a wavelength bandwidth memory unit 40 is provided, and in this wavelength bandwidth memory unit 40, the characteristics of the transiting wavelength bandwidth for the measured wavelength of spectrometer 5' are recorded. CPU 34 finds the wavelength bandwidth for each measurement point based on the recorded wavelength bandwidth. Next, the optical intensity values for each measurement point are calculated from the optical intensity measurement value for each measurement point the measurement values near the center of said measurement value regiondded over the range of the desired wavelength bandwidth, and further, compensated based on the ratio between the wavelength bandwidth for each measurement point and the wavelength interval of each measurement point.
