In a device for fitting and fixing a lens barrel into a cylindrical hole of a base, a notch extending from an edge of the fitting portion toward the diffraction grating is formed in the fitting portion of the holter of the diffraction grating, and the notch is inserted through the notch into the base. A fine adjustment mechanism for a diffraction grating, comprising: a hole through which the holder is exposed; and a jig that engages with the notch through the hole, and the jig allows the holder to rotate around the optical axis.
