ABSTRACT:
A spectrometer for correcting a displacement of a dispersed light image having a light source for outputting a monochromatic ray of light, an optical system which images a dispersed light image of the monochromatic ray through an incident slit on an imaging plane, a sensor array, and a calculator for calculating a variation in an imaging position of a primary dispersed light image of the monochromatic ray through the incident slit on the imaging plane from its initial position as a first image displacement amount, and a variation in an imaging position of a secondary dispersed light image of the monochromatic ray through the incident slit from its initial position as a second image displacement amount, and calculating, based on the first and second image displacement amounts, a third image displacement amount which is free of an influence due to a fluctuation of a wavelength of the monochromatic ray.
