Title:
ENDOSCOPE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/021388
Kind Code:
A1
Abstract:
This endoscope system includes: at least one excitation light source (LD2) that emits excitation light; at least one non-excitation light source (LD1, LD3 to LD7) that emits non-excitation light; an optical combiner (230) that combines the light path of the excitation light with the light path of the non-excitation light into a common light path; and a wavelength conversion unit (260) that includes a wavelength conversion member (262) which is arranged on the common light path. The wavelength conversion member transmits the non-excitation light and absorbs some of the components of the excitation light to generate wavelength converted light that has a wavelength different from the wavelength of the excitation light and emits illumination light that includes the transmitted non-excitation light and/or the generated wavelength converted light.
