PROBLEM TO BE SOLVED: To display a normal observation image and a special observation image (a spectral image) having high image quality without complicating an illumination optical system.SOLUTION: An endoscope device includes a light source unit wherein a first lamp 32 irradiating white light, a second lamp 34 irradiating narrowband special light, and a FP resonator 33 are combined, and the first lamp 32 and the second lamp 34 are installed such that the optical axes E1, E2 thereof intersect each other. An illumination optical system 40 including a rotor 42 formed with a mirror 42A and an aperture part 42B is positioned obliquely to the optical axes E1, E2 in a region wherein the optical axes E1, E2 intersect. While the illumination optical system 40 rotates, the white light is reflected on the mirror 42A while the special light is shielded by a light shielding surface 42Q, and the white light is led outside an optical path through the aperture part 42B while the special light passes through the aperture part 42B. Thereby, the white light and the special light are alternately incident on a light guide incident end 14A. |
