Assignee: SEIKO EPSON CORPORATION
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A light source apparatus comprising:
a light source configured to emit first light having a first wavelength band;
a wavelength converter configured to convert the first light into second light having a second wavelength band different from the first wavelength band;
a substrate supporting the wavelength converter;
an optical element disposed in an optical path of the first light to be incident on the wavelength converter;
a light collector configured to collect the first light emitted from the optical element toward the wavelength converter; and
a driver configured to rotate the optical element and the light collector around a rotation axis parallel to a first optical axis of the first light incident on the optical element,
wherein the optical element has a first surface on which the first light is incident along the first optical axis and a second surface via which the first light exits toward the light collector along a second optical axis,
the first light emitted from the light collector is incident on the wavelength converter along the second optical axis, and
the first optical axis and the second optical axis are shifted from each other.
