摘要： A high-performance image-forming optical system made compact and thin by folding an optical path using reflecting surfaces arranged to minimize the number of reflections. The image-forming optical system has a single prism. When image-side three surfaces of the prism are defined as a surface A, a surface B and a surface C in order from the image plane side thereof, at least one of the surfaces B and C has a rotationally asymmetric curved surface configuration that gives a power to a light beam and corrects aberrations due to decentration. The optical system leads light rays from an object to the image plane without forming an image in the prism and has a pupil in the prism. The surface A is a transmitting surface through which rays exit from the prism. The surfaces B and C are internally reflecting surfaces, which are positioned to face each other to form a Z-shaped optical path.

摘要： A de-centered optical system includes a first optical element having at least three surfaces surrounding a portion having a refractive index of more than 1, and a second optical element whose surface further from the first optical element is a convex surface and has a positive power and produces chromatic aberration of magnification. When the de-centered optical system is used as an ocular optical system of an image observation apparatus, the image size observed through the de-centered optical system in the blue wavelength is larger than that formed in the green wavelength, and that formed in the green wavelength is larger than that formed in the red wavelength. The difference can be compensated by an electronic compensation means. This optical system can be used as an image taking optical system by setting the light traveling direction inversely to that in case when it is used as an ocular optical system.

摘要： A compact image pickup optical system capable of providing a clear image of minimal distortion even at a wide field angle, and an image pickup apparatus using such an image pickup optical system. The image pickup optical system forms an object image on the surface of an image pickup device (8). At least a rear optical unit (4) is provided on the image side of a pupil plane (1). The rear optical unit (4) has at least one reflecting surface decentered such that the whole surface is tilted with respect to an axial principal ray (2) defined by a light ray emanating from the object center and passing through the pupil center to reach the image center. The reflecting surface has a rotationally asymmetric surface configuration that corrects rotationally asymmetric decentration aberrations caused by decentration, thereby reducing rotationally asymmetric aberrations of the object image.
