摘要： An optical system is disclosed for an endoscope having a generally tubular distal end in which an objective lens assembly and a solid-state video camera are internally housed so that an image formed by the lens assembly is focussed upon the video camera. The video camera is disposed along or in proximity to the center axis of the distal end of the endoscope. The video camera may be positioned in this way due to the provision of a reflecting surface which is angularly disposed in opposing relationship with an input surface of the video camera, and deflection means disposed in front of the lens assembly and within the objective lens assembly, or between the lens assembly and the reflecting surface, so that an image formed by the lens assembly can be focussed on the input surface of the video camera.

摘要： An illumination apparatus for an endoscope is provided at the distal end of the insertion section of the endoscope. The apparatus has a light guide which extends through the insertion section, has a light-issuing end located adjacent to the distal end opening of the insertion section. The light guide conducts light beams emitted from a light source device. An optical element made of a light-permeable material is arranged to face the light-issuing end of the light guide, and a lens is arranged in the distal end opening. The optical element has a light-receiving surface facing the light issuing end and a light issuing surface opposite to the lens. A depression is formed in the center of the light-issuing surface. Light beams emitted from the end of the light guide pass through the optical element and lens, and are distributed by the depression in the annular pattern whose central portions grow dark and whose peripheral portions are rendered bright.

摘要： An optical apparatus uses a variable-optical-characteristic optical element whereby focusing, zooming or the like can be effected without moving a lens or the like and the whole optical apparatus can be arranged in a lightweight structure. The user wears a power transmitting unit 303 by hanging it from his/her neck, for example. The power transmitting unit 303 may be put in a clothes pocket or the like. The power transmitting unit 303 may be placed somewhere around the user. In the power transmitting unit 303, a transmitting circuit 305 is driven by a power supply 304 to send an electromagnetic wave from a transmitting antenna 306 toward variable-focus eyeglasses 302. The variable-focus eyeglasses 302 have a receiving antenna 307 provided on eyeglass frames 308 to receive the electromagnetic wave sent from the power transmitting unit 303. The received electromagnetic wave is, for example, boosted in voltage and rectified to drive the variable-focus lenses.

摘要： A variable optical-property element includes a liquid crystal the pitch of twist is less than 60 times the wavelength of light used, so that a spatially uneven electric or magnetic field or temperature is applied to the liquid crystal to thereby form an index distribution, and the electric or magnetic field or the temperature is changed to thereby alter the index distribution. In this way, the variable optical-property element is capable of changing its optical properties as a liquid crystal lens and is used in an optical apparatus.

摘要： An optical unit is constructed by superposing and cementing the first substrate having fixed electrodes and the second substrate having a sheet-like member in which a moving plate-spring-like electrode is provided. Concentric through holes are provide at the middles of the sheet-like member of the first substrate and the second substrate, and an optical element, such as a lens, a mirror, or a prism, is mounted to the through hole of the sheet-like member. When voltages applied between the fixed electrodes and the moving electrode are controlled, the sheet-like member is displaced and thereby the optical element is deformed.
