At least one exemplary embodiment is directed to a projection optical system that projects an image of a pattern of a first object onto a second object includes a first image forming optical system, a second image forming optical system, and a light-shielding member. The first image forming optical system forms an intermediate image of the pattern, and includes a concave mirror and a reflecting mirror. The concave mirror has a reflecting surface opposing the second object. The reflecting mirror directs light from the first object to the concave mirror. The second image forming optical system forms an image of the intermediate image onto the second object, and includes a lens. The light-shielding member is disposed between the concave mirror and the lens.

It is possible to reduce the size of a magneto-optical device, increase the speed of optical control, simplify power supply structure and its control, and maintain a Faraday rotation angle in an arbitrary state even after shut-off of the excitation current. The magneto-optical device includes a magnetic yoke (10) made of a high-permeability magnetic material, the magnetic yoke including a tabular portion (16) and four pillar portions (18) protruding from one side of the tabular portion (16), a coil (12) wound on each of the pillar portions, and a magneto-optical element (14) arranged in an open-magnetic-circuit region surrounded by the end portions of the four pillar portions. A magnetic field obtained by a coil is applied to the magneto-optical element.
