Abstract: An endoscope system includes: a first light source that emits first light; a first light guide that guides the first light received from the first light source toward a subject; a second light source that emits second light having a different wavelength region from the first light; a second light guide that guides the second light received from the second light source toward the subject; and a blocker that alternatingly blocks the first light traveling from the first light source toward the first light guide and the second light traveling from the second light source toward the second light guide.

Abstract: A light source apparatus that is provided includes: a light source; a switch for switching the light path of irradiation light emitted by the light source between a first light path and a second light path; and an optical filter that is fixedly arranged in the first light path and filters irradiation light propagating along the first light path into light in a specific wavelength region.

Abstract: A medical-use light-source apparatus includes a light source lamp, a connector to which a body cavity endoscope and an ophthalmic observation apparatus can be selectively connected, a determiner which determines whether the body cavity endoscope or the ophthalmic observation apparatus is currently connected to the connector, and a lamp controller which sets a value of a maximum light amount of the illumination light to a first threshold value when the determiner determines that the body cavity endoscope is currently connected to the connector, and sets a value of a maximum light amount of the illumination light to a second threshold value that is smaller than the first threshold value when the determiner determines that the ophthalmic observation apparatus is currently connected to the connector.

Abstract: An optical low-pass filter is disposed on a light-receiving surface of an imaging device. The filter has a light-transmitting substrate including at least one birefringent plate and an infrared-cut plate , a dust-proofing layer provided on a light-input surface of the light-transmitting substrate, and an infrared-cut coat layer provided between the dust-proofing layer and the light-transmitting substrate or on a light-output surface of the light-transmitting substrate. A surface of the dust-proofing layer contains fine roughness.

Abstract: A therapeutic-substance carrying/administering appliance includes a cylindrical outer sheath; a slide member installed in the cylindrical outer sheath to be slidable therein; and a sheet supporting member, connected to a distal end of the slide member and made of a resilient material, for supporting a sheet-shaped therapeutic substance. The sheet supporting member is held in a flat unrolled shape in a free state in which the sheet supporting member projects outwardly from a distal end of the cylindrical outer sheath. When the sheet supporting member is in the free state, sliding the slide member in a retracting direction causes the sheet supporting member to contact the distal end of the cylindrical outer sheath, and subsequently further moving the slide member in the retracting direction causes the sheet supporting member to be retracted into the cylindrical outer sheath while being deformed into a tubular shape.

Abstract: The finder optical system has a reflex mirror, a focal plane plate, a prism, an eyepiece, and a dust-proofing multilayer. The reflex mirror is disposed on an optical path of a photographing optical system. The focal plane plate is disposed at a position on which an image is formed by a light which passes through the photographing optical system and which is reflected by the reflex mirror. The light-input surface of the prism races a light-output surface of the focal plane plate. The eyepiece faces a light-output surface of the prism. The dust-proofing multilayer, which is provided on a surface of the focal plane plate, has a water-repellent or water- and oil-repellent layer and an anti-static layer.

Abstract: An anti-reflection spectacle lens has an anti-reflection film composed of a plurality of layers formed on at least one surface of a lens substrate or other one or more layers formed on said lens substrate, the anti-reflection film comprising an outermost layer made of silicon oxide, on which a water- and oil-repellent layer is formed by vacuum deposition. The spectacle lens is excellent in water and oil repellency, and aqueous stains and oily stains attached to the spectacle lens can easily be wiped off. The use of a pellet impregnated with a hydrophobic, reactive organic compound in a vacuum deposition chamber contributes to the reduction of a production cost.
