Claim 4:
5. The Fourier spectrophotometer according to claim 1,
wherein the interferometer comprises:
a half mirror configured to branch the light emitted from the light source into a first branch light and a second branch light, and cause the first branch light and the second branch light passing through different optical paths to interfere with each other to obtain the first interferogram and the second interferogram;
a fixed mirror configured to reflect the first branch light branched by the half mirror and cause the first branch light to be incident on the half mirror;
a moving mirror configured to be able to reciprocate along an optical path of the second branch light, reflect the second branch light branched by the half mirror, and cause the second branch light to be incident on the half mirror;
a first output configured to output the first interferogram to the outside; and
a second output configured to output the second interferogram to the outside.
