Abstract

PURPOSE:To provide a double spectroscope provided with a simple wavelength feed mechanism of high accuracy without requiring any connecting mechanism by using one wavelength feed screw mechanism and letting the same serve as two sine bar mechanisms in the double spectroscope using two diffraction gratings. CONSTITUTION:The double spectroscope has a diffraction grating of a grating constant a and a diffraction grating 5 of a grating constant b. The length between the rotating center GA of the diffraction grating 4 and the center point CA of the roller 7 at the end of a lever 6 is let to be la and the length between the rotating center point GB of the diffraction grating 5 and the center point CB of the roller 9 at the end of a lever 8 to be lb. The roller 7 and roller 9 are pressed by springs to the end face 10 of the slider 3 capable of advancing in the axial direction of the feed screw 3. If these are set at la:lb = a:b and the points GA, GB, CB are in the alignment in the case of zero order light, then the spectroscope having the diffraction grating 4 and that having the diffraction grating 5 become always the same in wavelength even if the feed screw 2 is rotated. If the spectroscopes are let phiA, phiB by using the diffraction gratings 4, 5, la:lb is brought to the relation of the formula (A).
