    摘要： A zoom lens includes a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit having a positive refractive power. The first, second, and third lens units are arranged in that order from an object side to an image plane side of the zoom lens. The first lens unit includes a first lens having a negative refractive power, the second lens unit includes a second lens having a positive refractive power and a third lens having a negative refractive power, and the third lens unit includes a fourth lens having a positive refractive power. During zooming from a wide-angle end to a telephoto end, the first lens unit is fixed, and the second lens unit and the third lens unit are moved.

    摘要： The present invention includes, from an object side to an image-plane side: an aperture stop with a predetermined diameter, a first lens with a positive refractive power having a convex surface on the object side, a second lens with a positive refractive power having a concave surface on the object side, and a third lens with a negative refractive power having a convex surface on the object side. The second and third lenses have aspherical surfaces on their object-side and image-plane-side surfaces. The third lens is formed with an inflection point where the curvature orientation changes within the effective diameter range of the aspherical surface on the image-plane side. An appropriate back focus is maintained while the total length of the lens system is reduced. A compact, thin, high-performance design is achieved, which effectively corrects various aberrations, especially astigmatism and distortion, and is suited for digital cameras using high-density solid-state imaging elements of one million pixels or more.

    摘要： An imaging lens includes, in sequence from the object side to the image plane side: a first lens with a convex object side surface and having a positive overall index of refraction; an aperture stop having a predetermined diameter; a second lens with a convex object side surface and having an overall positive index of refraction; and a third lens with a concave object side surface and an overall negative index of refraction. At least one surface of the first lens is formed as an aspherical surface. Both surfaces of the third lens are formed as aspherical surfaces, with the image side surface having an inflection point at which the curvature of the surface changes within the effective diameter range. The imaging lens provides superior optical characteristics and is compact and suited for use in mobile cameras installed in portable telephones, PDAs, and the like.

    摘要： A method of producing an elliptic core type polarization-maintaining optical fiber comprises the steps of providing a glass rod comprising a cladding glass layer around the periphery of a core glass layer, the cladding glass layer having a softening point higher than the softening point of the core glass layer, removing two side surface portions of the glass rod by machining along the axial direction of the glass rod to form a machined rod noncircular in cross section, outside depositing fine silica glass particles on the periphery of the machined rod, followed by sintering to provide a support glass layer having a softening point higher than the softening point of the cladding glass layer, and drawing the thus obtained glass rod body as an optical fiber preform. Since the portion for constituting the core of the optical fiber is formed by machining, the core is permitted to have a high ellipticity. An optical fiber with the desired size and birefringence index is obtained by regulating the conditions of production.
