Abstract: An endoscope light source device includes a light source to emit light, and a speckle reduction member to scatter the light. The reduction member has a surface including thickness variation to provide the light with an optical path difference. The device also includes a drive to move the reduction member, and a lens to condense the light passed through the reduction member onto a light guide of an endoscope. The surface of the reduction member has inclination of an average inclination angle. The average inclination angle is determined so that a light quantity loss rate of the entering light into the light guide by scattering of the reduction member and refraction of the lens has a positive value equal to or smaller than an effective allowable loss rate.

Abstract: A light source device includes a first semiconductor light source, a second semiconductor light source, and a wavelength converter. The first semiconductor light source emits light in a first wavelength range. The second semiconductor light source emits light in a second wavelength range different from the first wavelength range. The wavelength converter absorbs the light in the first wavelength range to emit light in a third wavelength range different from either of the first wavelength range and the second wavelength range, and transmits the light in the second wavelength range substantially entirely.

Abstract: A bending apparatus includes a shape sensor including a light source, an optical fiber, a detecting part, and a light receiver. The shape sensor utilizes a variation in optical characteristics, which is detected by the detecting part in accordance with a variation of curvature of the optical fiber when the optical fiber is bent. The shape sensor is freely bendable in any direction and having directivity in detection sensitivity for a bending direction. A bending direction restriction mechanism is combined with the shape sensor and has bending directivity including such a property of ease in bending that bending is easy in at least a specific direction other than a direction of a center line, and such a property of difficulty in bending that bending is difficult in directions other than the specific direction.
