    Abstract: Disclosed is a Fourier transform spectroscope having a control interferometer capable of facilitating optical axis adjustment and miniaturization by reducing the number of optical elements. Using a first reflection mirror 131 provided with a reflection surface 131a configured to reflect measurement light emitted from a measurement light source 110 toward a beam splitter 140 and a first through-hole 131b extending along an optical axis direction of the measurement light reflected on the reflection surface 131a and a laser light source holding portion configured to hold a laser light source 120 such that laser light emitted from the laser light source 120 is incident to the beam splitter 140 through the first through-hole 131b, optical axes of the measurement light and the laser light are aligned with each other. Since a laser reflection mirror for aligning the optical axes of the measurement light and the laser light of the related art is not necessary, it is possible to reduce the number of parts and facilitate optical axis adjustment and miniaturization.
