PROBLEM TO BE SOLVED: To provide a multi-screen spectral photographing device that allows a single imaging element to form a plurality of images resulting from optically separating a primary image of an object without parallax or less parallax to a plurality of wavelength bands nearly, substanstantially at the same time, with high accuracy and displays the images on a monitor. SOLUTION: The multi-screen spectral photographing device is provided with a fiber optic plate 4 having a light receiving end face 4a on which an image of an object 2 is formed by an objective lens 3 as a primary image and an output optical end face 4b, to which a primary image formed on the light-receiving end face is delivered, total reflection mirrors 6a-6d that optically split an optical path of the image from the output light end face of the fiber optic plate into a plurality of optical paths 7a-7d, interference filters 8a-8d that optically separate the image of each optical path separated by the total reflection mirrors into images with a plurality of wavelength bands respectively, a dual slope reflection right angle prism 10 that lays out a plurality of the images separated by the interference filters in a prescribed direction to composite them into a single image, a reduction optical system 12 that optically reduces the magnification of the images from the dual slope reflection right angle prism 10, and a CCD image pickup element 11 that photographs a plurality of the images from the reduction optical system with a single image pickup face 11a nearly at the same time. |
