の照明機構。 In the illumination optical system of a binocular indirect ophthalmoscope, in which the illumination optical system such as a light source, condenser lens, objective lens, and reflection mirror is disposed within the body, an illumination field is placed on the optical path of the light source through the condenser lens. In addition to inserting a diaphragm for changing the angle, the position of the mirror is moved back and forth or up and down with respect to the incident optical axis in order to change the angle that the illumination optical axis that has passed through the reflection mirror makes with the observation axis. The movement of the mirror is coupled so that when the mirror is moved to a side that reduces the angle that the illumination optical axis makes with the observation axis after passing through the mirror, the aperture diaphragm is operated in conjunction with the side that is narrowed down. Illumination mechanism of binocular indirect ophthalmoscope.
