    摘要： This invention relates to a multifocal optical lens configuration that relies on the phenomenon of simultaneous vision whereby the eye is presented with two clear images at once. In particular this invention allows a lens to be made with arbitrary relative brightnesses between the multiple images. Thus, for example, the lens can comprise a carrier lens CL, the anterior surface I of which is divided into six concentric annular zones, bounded by radii r1-r6 in such a manner as to form a trifocal phase plate.

    摘要： There is provided a method for producing an optical system, the method comprising the steps of,
    a) providing at least a first mold part to provide a first mold cavity for an intermediate product with a surface,
    b) providing a lens forming fluid in the first mold cavity, and allowing the lens forming fluid to solidify, to produce an intermediate product with a surface,
    c) coating at least a part of the surface of the intermediate product with a material to produce an optical element in the optical system, where the material is different from the lens forming fluid,
    d) providing at least a second mold part for the optical system,
    e) arranging the intermediate product in relation to the second mold part to provide a second mold cavity such that the coating applied in step c) is exposed to the second mold cavity and
    f) providing lens forming fluid in the second mold cavity such that the coating applied in step c) becomes embedded in the lens forming fluid, and allowing the lens forming fluid to solidify.

    摘要： A multifocal system and a method thereof are provided. The multifocal system comprises a first adaptive lens assembly including a plurality of lenses arranged in optical series. The plurality of lenses includes at least one active liquid crystal (LC) lens having a plurality of optical states, such that the plurality of lenses provides a plurality of combinations of optical power, and the plurality of combinations of optical power provides a range of adjustment of optical power for the multifocal system. The multifocal system may include a second adaptive lens assembly configured to provide a plurality of combinations of optical power that is opposite to but having a same absolute value as the plurality of combinations of optical power provided by the first adaptive lens assembly.

    摘要： A light emitting device (1) includes a first light emitting element (30), a first light reflecting member (40) and a lens member (50). The first light reflecting member (40) is positioned with respect to the first light emitting element (30) so that emitted light from the first light emitting element (30) is divided into a portion of the emitted light from the first light emitting element irradiating onto the light reflecting face (41) of the first light reflecting element (40) and a portion of the emitted light from the first light emitting element (30) traveling outside of the light reflecting face (41) by having an edge of the light reflecting face (41) serve as a boundary. The lens member (50) includes a reflected light passing region having a first lens shape (51) configured to control the travelling direction of reflected light, and a non-reflected light passing region having a second lens shape (52) configured to control a travelling direction of non-reflected light.

    摘要： A lens moving device is provided. The lens moving device includes: a bobbin; a first driving unit coupled to the bobbin; a second driving unit configured to move the first driving unit through an electromagnetic interaction with the first driving unit; a sensing magnet disposed on one side of the bobbin; a location detection sensor configured to sense a location of the sensing magnet; and a correction magnet disposed on an opposite side of the bobbin.
    According to the present disclosure, static tilt and dynamic tilt of the bobbin, to which a lens module is to be coupled, may be enhanced by a sensing magnet and a correction magnet which establish magnetic force equilibrium with each other.
