ABSTRACT:
A spectroscopic apparatus capable of simultaneously producing spectroscopic images corresponding to a plurality of wavelengths and a spectroscopic image recording apparatus capable of recording the produced spectroscopic images, wherein an image producing unit produces a plurality of same images from a single input image by dividing a pupil of an optical system, a first spectroscopic unit produces a plurality of first spectroscopic images corresponding to the plurality of same images by extracting a predetermined wavelength component corresponding to each of the plurality of same images, and a second spectroscopic unit produces a plurality of second spectroscopic images corresponding to respective ones of the first spectroscopic images by extracting a predetermined wavelength component corresponding to each of the first spectroscopic images corresponding to the plurality of same images.
