摘要:
A fluorescent type of green light source of a semiconductor in a light source apparatus for an endoscope includes a blue excitation light source device and green emitting phosphor. The blue excitation light source device emits blue excitation light. The green emitting phosphor is excited by the blue excitation light, and emits green fluorescence. A dichroic filter in a dichroic mirror cuts off the blue excitation light from an emission spectrum of mixed light of the blue excitation light and green fluorescence from the fluorescent type of green light source. Thus, illumination light with the emission spectrum of a target can be stably supplied without influence of the blue excitation light to a light amount of blue light from a blue light source of a semiconductor.
