A surgical observation system provided with a supporting arm movable in the three-dimensional direction includes an endoscope objective unit having a tubular insertion section and provided with objective optical systems, a microscope objective unit provided with objective optical systems having a focusing optical system and variable magnification optical systems, and a mounting and dismounting section provided in the supporting arm, mountable and dismountable with respect to the objective units by having interchangeability. The objective optical systems provided in each of the objective units are constructed so that light beams emerging therefrom toward the mounting and dismounting section are changed to afocal light beams, and the mounting and dismounting section is provided with a pair of imaging lenses and a pair of image sensors and is constructed so that, in a state where the objective unit is mounted to the mounting and dismounting section, the objective unit is optically connected with the mounting and dismounting section. |
