摘要： An optical communication device includes a light source that emits a light beam and an optical fiber having a core and a cladding. The optical fiber has a light entrance face having a core region and a cladding region. The light beam emitted by the light source is converged by a converging lens on the core region and is transmitted through the optical fiber. The entrance face is configured to generate a light intensity distribution in light reflected by the light entrance face depending on a position where the light beam is incident on the entrance face, a converging lens arranged between the light source and the optical fiber.

摘要： An optical fiber includes an entrance face that is optically coupleable with a device for transmitting a light beam through the optical fiber. The entrance face includes a core region and a cladding region surrounding the core region. The cladding region is at least partially covered with a coating, which is made of metal, for example. That is, the coating is formed over a whole area of the cladding region or the coating is formed on an area of the cladding region defined in a vicinity of the core region. The coating has a mirror surface to increase the reflectivity thereof and enhances the reflectivity of the entrance face.

摘要： Disclosed is a single-vision astigmatic-power spectacle lens having cylindrical power to correct astigmatism of an eye. The spectacle lens has front and back surfaces, one of which is a rotationally-asymmetrical aspherical surface. The rotationally-asymmetrical aspherical surface has a first rotationally-asymmetrical component to add said cylindrical power for correcting astigmatism of an eye and a second rotationally-asymmetrical component to correct the aberrations in the directions between first and second principal meridians caused by adding the cylindrical power. That is, when the sag z(h, &thgr;) is expressed as a function of the angle &thgr; while fixing the distance h from the center, a curve of the function has a larger gradient in close to the local maximum and a smaller gradient in close to the local minimum as compared with the curve interpolated by the sine curve.

摘要： A back-surface progressive power lens is provided having a negative dioptric power for distance vision, the value of a surface power Pfm of the progressive surface in the main meridional plane at a first point on the main meridian in a distance portion of the progressive power lens is less than the value of a surface power Pfs of the progressive surface in a plane perpendicular to the main meridional plane at the first point; and the value of a surface power Pnm of the progressive surface in the main meridional plane at a second point on the main meridian in a near portion of the progressive power lens is greater than the value of a surface power Pns of the progressive surface in a plane perpendicular to the main meridional plane at the second point. The surface power P is defined by the following condition: P=(n−1)/r; wherein “n” represents the refractive index of the progressive power lens, and “r” represents the radius of curvature at one of the first point and the second point on the main meridian in the near portion and the distance portion, respectively.

摘要： Disclosed is a manufacturing method of a spectacle lens. The entire range of available vertex power of a spectacle lens is divided into a plurality of sections, and a plurality of types of semifinished lens blanks that are different in base curve are prepared for each of the sections. On the basis of required vertex power, choices of lens blanks are narrowed down. The plurality of types of the semifinished lens blanks can be selected for a specific vertex power. A customer selects one type of the semifinished lens blank based on weightings of optical performance and outward appearance. Further, a back surface of the selected semifinished lens blank is processed to form a finished lens according to a required specification for the spectacle lens.

摘要： Disclosed is a manufacturing method of a spectacle lens. The entire range of available vertex power of a spectacle lens is divided into a plurality of sections, and at least one type of semifinished lens blank whose front surface is finished is prepared for each of the sections. On the basis of required specification, one type of the semifinished lens blank is selected. Further, an aspherical shape design for processing the back surface of the selected semifinished lens blank is determined according to the required specification. The aspherical shape of the back surface is optimized such that average power errors or astigmatisms of the finished lenses having different vertex powers within the same section are approximately balanced. Finally the back surface is processed based on the determined aspherical shape.
