Light source deviceFrom incident lightA first optical element for generating reflected light obtained by removing the first wavelength band component and the first wavelength band component from incident lightEmit light containing at least a component of the first wavelength bandA first light source to be incident on the first optical element to be reflected light of said first optical elementA second light source for emitting light such that a light containing a component of a wide second wavelength band including the first wavelength band is transmitted light of the first optical elementA control unit for controlling drive of said first light source and said second light source.The control section selectively controls the output of the first light source outgoing light and the on / off of the light emission from the second light source, thereby selectively emitting the first light and emitting the second light.光源装置は、入射光から、第１波長帯域の成分を除去した透過光と入射光から第１波長帯域の成分を抽出した反射光を生成する第１光学素子と、前記第１波長帯域の成分を少なくとも含む光を出射し、前記第１光学素子の反射光となるように前記第１光学素子に入射させる第１光源と、前記第１波長帯域を含む広い第２波長帯域の成分を含む光が前記第１光学素子の透過光となるように光を出射する第２光源と、前記第１光源及び前記第２光源の駆動を制御する制御部と、を有する。前記制御部は、前記第１光源出射光の出射と前記第２光源出射光の出射のオン／オフを制御することにより、前記第１の光の出射及び前記第２の光の出射を選択的に行う。
