A structure that changes from a confocal observation mode to a normal observation mode is made possible while keeping a Nipkow disk in a fixed position. A main optical system includes a confocal illumination light source, a first half mirror, a Nipkow disk, an objective lens, a relay lens and an ocular lens for conducting confocal observation. A bypass optical system includes a normal illumination light source, a second half mirror and first, second and third fully reflective mirrors. The bypass optical system is appended to the main optical system to form the tandem scanning confocal microscope. The first and third fully reflective mirrors can be moved out of and separated from the light path of the main optical system. As a result, with the position of the Nipkow disk fixed, it is possible to change between confocal and normal observation modes.
