ILLUMINATION OPTICAL SYSTEM FOR ENDSCOPE AND ENDOSCOPE |
摘要 |
A wide range is illuminated with a sufficient light amount while a diameter of an insertion portion is reduced. Provided is an illumination optical system for endoscope including an optical fiber for guiding excitation light emitted from a light source; a first mirror and a second mirror disposed facing a light emission end at a distal end of the optical fiber and diffusing the excitation light emitted from the light emission end; and a phosphor on which the excitation light diffused by the first mirror and the second mirror is incident and which emits fluorescence. |

1. An illumination optical system for endoscope comprising:
a light guide member for guiding excitation light emitted from a light source; a light diffusing member which is disposed facing a light emission end at a distal end of the light guide member and diffuses the excitation light emitted from the light emission end; and a phosphor on which the excitation light diffused by the light diffusing member is incident, the phosphor emitting fluorescence. |
