摘要： Disclosed is an image capturing apparatus comprising a primary mirror 1 that has a surface which is a section of a surface cut out from a paraboloid with a single focus; a secondary mirror 2 that has a surface which is a section of a surface cut out from a hyperboloid with two foci; and a photodetector 3 which converts the light signal coming from the secondary mirror 2 into an electric signal. The secondary mirror 2 is placed in a position where one of its foci and the focus of the primary mirror 1 match with each other. The photodetector 3 is placed near the other focus of the secondary mirror 2. By using two mirrors, the light from the object is led to the photodetector 3 without being shaded.

摘要： Provided is a compact and bright imaging optical system having a high resolution. The imaging optical system includes three reflectors composed of a first reflector (1), a second reflector (2), and a third reflector (3) that are arranged in this order on an optical path of incident ray so as not to block the incident light. In the imaging optical system, in which light beams reflected by the three reflectors form an image plane (4), a convex mirror is used for any one of the first reflector (1) and the third reflector (3) and a concave mirror is used for the other thereof, and vertexes of a triangular dipyramid (6) are defined in terms of a central chief ray (5) by an appropriate point on the central chief ray (5) that is incident to the first reflection surface, a reflection point of each central chief ray on the first to third reflection surfaces, and an image forming point of the central chief ray. A plane containing three reflection points of the central chief ray on the first to third reflection surfaces coincides with a bonding plane between two triangular pyramids forming the triangular dipyramid (6).

摘要： A bright wide-angle catoptric system is provided which will not deteriorate the picture quality of images. The wide-angle catoptric system includes, successively from an object, a secondary reflecting mirror having a concave surface, a primary reflecting mirror having a convex surface and a tertiary reflecting mirror having a concave surface, and produces images by reflecting the luminous flux from the object at the primary reflecting mirror, the secondary reflecting mirror and the tertiary reflecting mirror successively. The system also includes a diaphragm arranged in close proximity to the primary reflecting mirror so as to have an optical axis pass through the center of the diaphragm; the optical axis is a straight line connecting the curvature center of the primary reflecting mirror to the curvature center of the secondary reflecting mirror. The tertiary reflecting mirror has its curvature center decentered from the optical axis in the direction of lesser astigmatism.

摘要： A field flattener having a function of flattening a bent image surface on which an image is formed through an optical system, is composed of a material of which a refractive index is equal to or larger than 2. A sectional configuration of the field flattener cut in an optical-axis direction containing the optical axis is formed to take a stepped shape toward its peripheral edge from the optical axis. An axial height of the stepped portion configuring the surface in the optical-axis direction in this stepped shape is set so as to equal to or larger than twice a wavelength of beams to be used.

摘要： An infrared optical system for infrared cameras has a convex lens held by a holding member composed of a low-dispersion material that transmits infrared light. A stop for restricting light beams entering the convex lens is disposed on an object side from the convex lens. An aberration correcting plate for reducing spherical aberration is provided in the vicinity of the stop. A field flattener, the thickness of which changes along image height to offset curvature of field, is disposed on an image side of the convex lens.
