PROBLEM TO BE SOLVED: To provide a spectroscope using liquid crystal, light in weight, light in transmission light, capable of obtaining high spectrum precision, and moreover is capable of being manufactured easily. SOLUTION: The spectroscope is constituted, such that for an interferometer 10 for light separation with the Fourier transform spectrometer which uses a liquid crystal panel 10A, in which one or multiple liquid crystal cells 12 are held between a pair of polarizers 11 and 13, with the light 1 incident on the liquid crystal panel is divided into two components of normal light 1A and abnormal light 1B; and by varying the cell voltage of the liquid crystal cells, the optical path differenceδbetween the two components is generated, and the resultant interference light 2 is emitted.
