Abstract:
1. A light source apparatus comprising: an excitation light source including a laser light source; a first wheel that is controlled to rotate, includes a phosphor layer to be excited by excitation light emitted from the excitation light source, and reflects fluorescence emitted from the phosphor layer, in a direction from which the excitation light has been incident; a dichroic mirror that is provided between the first wheel and the excitation light source, and guides the fluorescence and the excitation light to an illumination optical system; and a second wheel that is controlled to rotate, is provided between the dichroic mirror and the illumination optical system, and includes a dichroic filter that guides light having a desired wavelength component of each of the fluorescence and the excitation light to the illumination optical system.
