More Information
Summary:An endoscope system includes: an excitation light source to emit excitation light; non-excitation light sources to emit non-excitation light; an optical combiner configured to integrate optical paths of the excitation light and non-excitation light into a common optical path; and a wavelength conversion unit including a wavelength conversion member disposed on the common optical path. The wavelength conversion member transmits the non-excitation light, absorbs part of the excitation light to generate wavelength-converted light, and emits illumination light including the non-excitation light and wavelength-converted light. Spectra of the non-excitation light each have a peak wavelength in a wavelength band out of a wavelength band of a spectrum of the wavelength-converted light.
