The invention discloses an endoscope system, wherein an LPF turntable and an SPF turntable are arranged in a wide-band light path (BB). The LPF turntable is provided with a first LPF and a second LPF, wherein the lower limits of the wavelengths of the first and second LPFs are different from each other. The SPF turntable is provided with a first SPF and a second SPF, wherein the upper limits of the wavelengths of the first and second LPFs are different from each other. The wide-band light (BB) can pass through the LPFs and the SPFs, so that a blue arrow-band light with a predetermined half-value width is generated. |
