Prism optical system and image pickup apparatus using the same

Abstract

The present invention relates to a compact and high-performance prism optical system having, in order in which rays pass from the object side, a first transmitting surface (4), a first reflecting surface (5), a second reflecting surface (6), a third reflecting surface (7), a fourth reflecting surface (8), and a second transmitting surface (9). The first transmitting surface (4) and the second reflecting surface (6) are formed from the identical surface, and the second transmitting surface (9) and the third reflecting surface (7) are formed from the identical surface. The first reflecting surface (5) and the fourth reflecting surface (8) are formed from surfaces independent of the first transmitting surface (4) and the second transmitting surface (9). At least one of the reflecting surfaces is formed from a rotationally asymmetric surface. At least one of the second reflecting surface (6) and the third reflecting surface (7) has a power.
