Abstract
A wavelength conversion apparatus according to an aspect of the present disclosure includes a wavelength converter that converts first light emitted from a light source and having a first wavelength band into second light having a second wavelength band different from the first wavelength band, a base to which the wavelength converter is fixed, a light collector that causes the first light emitted from the light source to enter the wavelength converter, a holding part that holds the light collector, a rotary driver that rotates the holding part around an axis of rotation, and a support part that is fixed to the base and rotatably supports the holding part, the optical axis of the light collector is separated from the axis of rotation of the holding part, the optical axis of rotation of the holding part is parallel to the axis of rotation of the holding part.
