Abstract
An objective optical system includes a lens group and an optical-path splitting element. The optical-path splitting element has an optical-path splitting surface which forms a first optical path and a second optical path. A reflecting surface is positioned in the second optical path and a predetermined optical surface is positioned in the second optical path. A wavelength band of light transmitted through the predetermined optical surface or a wavelength band of light reflected at the predetermined optical surface is restricted. The wavelength band which is restricted is narrower than a wavelength band of light that travels along the other optical path. A quarter-wave plate is positioned between the optical-path splitting surface and the reflecting surface. The optical-path splitting surface has a characteristic of transmitting P-polarized light and reflecting S-polarized light. The predetermined optical surface is positioned between the optical-path splitting surface and the quarter-wave plate.
