PURPOSE:To reduce the size by sharing parts of the optical axes of an illumination optical system, a measurement projection optical system, and a photodetection optical system. CONSTITUTION:This microscope is equipped with the illumination optical system 50 which lights the eyeground through an objective 31, the measurement projection optical system 60 which projects measurement luminous flux upon the eyeground Er through the objective 31, and the photodetection optical system 70 which photodetects the reflected luminous flux of the measurement luminous flux through the objective 31. The optical axis 60a of the measurement light projection system 60 and the optical axis 70a of the measurement light projection system share the same optical axis partially. Further, the optical axis of the photodetection optical system 50 and the optical axis 70a of the measurement projection optical system share the same optical axis partially. Consequently, the illumination optical system 50, measurement optical system 60, and photodetection optical system 70 share the same optical axis partially. Consequently, the microscope for operation can be reduced in size. |
