    摘要： A method of producing optical components includes providing an initial carrier including cutouts; carrying out a molding process to form transparent optical molded parts arranged in the cutouts of the initial carrier, wherein a molding compound is introduced into the cutouts of the initial carrier and the molding compound is molded and cured; and singulating the initial carrier including the optical molded parts so that separate optical components are formed that respectively include a carrier produced from the initial carrier and including a cutout, and an optical molded part arranged in the cutout.

    摘要： A multilayer diffractive optical element includes a first substrate, a second substrate, a first resin layer having a first diffraction grating pattern and interposed between the first substrate and the second substrate, and a second resin layer having a second diffraction grating pattern and interposed between the first substrate and the second substrate. The first resin layer includes a first region provided at a peripheral portion adjacent to a portion of the first diffraction grating pattern. The first resin layer includes a second region provided at a peripheral portion adjacent to the first region.

    摘要： A method for fabricating a Fresnel lens or other lens having a structured surface such as refractive and/or diffractive bi-focal or other multi-focal lenses includes press-coating the structured surface with a low or very low refractive index coating material. The coating is sufficient thick to adequately cover the structured surface so that a smooth coating surface with good optical properties is obtained, for example in the case of a Fresnel structure a thickness greater than 1.5 times and less than 5 times the Fresnel structure height, and is cured in situ. A film, e.g., of PET, PC or PU or a film stack, e.g. a TAC/PVA/TAC film stack is prepared and a heat melting adhesive is applied to the side of the film or film stack to be contacted with the coated structured surface of the lens blank. The film or film stack is then laminated to the cured coating.

    摘要： A tunable optical diffraction grating apparatus, such as but not limited to a tunable Fresnel zone lens apparatus, includes a plurality of symmetric repeating structures (i.e., typically concentric rings) located over a substrate and comprising a material susceptible to a transparent to opaque transition for a designated radiation wavelength. The tunable optical diffraction grating apparatus also includes a means for separately effecting the transparent to opaque transition for each of the plurality of symmetric repeating structures to provide a plurality of transparent zones each comprising a variable first sub-plurality of adjacent transparent symmetric repeating structures alternating and interposed between a plurality of opaque zones each comprising a variable second sub-plurality of adjacent opaque symmetric repeating structures. Also included are a method for fabricating the tunable optical diffraction grating apparatus and a method for operating the tunable optical diffraction grating apparatus.
