摘要： An optical element is made of a transparent medium that is rotationally symmetric relative to the central axis with a refractive index greater than 1. The transparent medium has a first transmissive surface at the outermost periphery relative to the central axis, a first reflective surface at the side of the central axis relative to the first transmissive surface, a second reflective surface at the side opposite to the image plane relative to the first reflective surface and a second transmissive surface at the side of the image plane relative to the second reflective surface. The flux of light enters and proceeds through the transparent medium via the first transmissive surface, the first reflective surface, the second reflective surface and the second transmissive surface to form an optical path. The optical path is formed only at a side relative to the central axis.

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： The invention relates to a panoramic attachment optical system and a panoramic optical system for taking an image having a full 360°-direction angle of view or projecting an image at a full 360°-direction angle of view. These optical systems are reduced in size and flare light and improved in resolving power. A panoramic attachment optical system 10 attached to the entrance side of an image-formation lens 20 to form a full 360°-direction image on an image plane 30 comprises a transparent medium that is rotationally symmetric about a center axis 1 and includes at least one internal reflecting surface 12 and at least two refracting surfaces 11 and 13. A light beam incident on the entrance surface 11 in order of travel of light enters the transparent medium via the entrance surface 11, and is reflected at the internal reflecting surface 12 to leave the transparent medium via the exit surface 13, forming an image at a position of the image plane 30 off the center axis 1 via the image-formation lens 20. The internal reflecting surface and the refracting surfaces are each of shape rotationally symmetric about the center axis 1, and a light beam 2 coming from far way forms an image at least one time in a section including the center axis 1, but does not form any image in a plane that is orthogonal to that section and includes a center ray 20 of that light beam.
