    Abstract: An image-pickup optical system includes: a first lens provided near an aperture stop and configured to correct aberration; and a second lens arranged between the first lens and an image sensor and configured to collect light, the first lens being a gradient index lens. The degree of freedom of design of a gradient index lens is higher than that of a lens having a constant refractive index, and a gradient index lens thus has a high potential as a device for a lens. Because such a gradient index lens is employed, it is possible to correct aberration without performing expensive processing such as polishing for example. In other words, as a result, costs may be reduced and image-forming properties may not be reduced at the same time.

    Abstract: A method of manufacturing lenses includes creating a wafer-level master, overmolding the wafer-level master to form a daughter replica, casting a polymer lens shapes onto a wafer using the daughter replica, transferring the polymer lens shapes into the wafer, and singulating the wafer to create individual dies with a lens thereon. The wafer may be silicon, e.g., silicon having a resistivity between 0.1 and 100 ?cm.

  • Publication number: 20150103182
    Abstract: There is provided an infrared optical system includes a light collecting lens having a curved light collecting surface for collecting infrared light incident from an object side, the lens being made of resin having a stepped shape being gradually deeper from periphery to center; and an optical path length correction element for correcting a difference in an optical path length produced by the stepped shape of the light collecting lens. The above-described stepped shape is provided to allow the lens to be thinner than the lens having the plano-convex shape. In other words, the infrared transmittance of the optical system is improved. In addition, the optical path length correction element can correct a difference in an optical path length produced by the stepped shape of the light collecting lens.

  • Publication number: 20150090862
    Abstract: A lens reflecting a light of a predetermined wavelength, or transmitting and condensing or diverging the light is provided. The lens includes a substrate, and a quasi-periodic structure layer. A plane of the quasi-periodic structure layer is divided into unit cells and is filled with the unit cells in a two-dimensional period. The unit cell has a first region and a second region. An occupancy rate is changed as a distance from a center of the substrate. A resonance mode is defined by a relationship between the occupancy rate and the period length. A lowest order resonance mode is defined by the resonance mode. The period length is set to a predetermined value within a predetermined range including an optimum value. Another lens is provided. A minimum occupancy rate is defined by a smallest occupancy rate. A variation range of the occupancy rate changes across the minimum occupancy rate.

  • Publication number: 20150022668
    Abstract: The invention relates to a lighting apparatus (1) comprising an array (2) of light sources (3) emitting emission cones (4) with edges (5) which intersect in an intersection plane and a lens unit (7) for homogenizing the intensity distribution in the far field. The array of the light sources and the lens unit are arranged such that i) the emission cones traverse the lens unit and ii) the distance (s) between the array of the light sources and the lens unit deviates from the sum of or the difference between a) the focal length f of the lens unit and b) the distance t between the intersection plane and the array (2) of the light sources (3) by 20 percent or less. This configuration leads to an intermixture of the emission cones in the far field such that the intensity distribution in the far field is substantially homogeneous.
