    摘要： An optical element, e.g. based on a diffractive Fresnel lens, having suppressed or reduced chromatic aberration under non-monochromatic light and/or enhanced directional homogenisation in its angular irradiation characteristics, comprises a plurality of optical zones (10, 20), wherein each zone comprises at least one homogenising noise-introducing feature. In embodiments the at least one homogenising noise-introducing feature comprises one or more zonal displacement features, e.g. ripples (20′, 20″) and/or one or more zonal modulation features, e.g. one or more patterning features (30).

    摘要： An optical element (1) comprises: a body (2) of radiation converting monocrystalline material, e.g. of a luminescent or scintillator material, and an extraction structure (4, 6) applied to at least one output and/or input surface of the body (2) of radiation converting monocrystalline material; wherein the extraction structure (4, 6) is constructed and configured such that radiation at an output (19) of the body (2) of radiation converting monocrystalline material is directionally modified, as compared with radiation at the output of the body (2) of radiation converting monocrystalline material in the absence of said extraction structure (4, 6), by interaction of radiation entering and/or propagating within and/or exiting the body (2) of radiation converting monocrystalline material with the said extraction structure (4, 6), e.g. by: i) modifying the energy or intensity of the radiation at the output (19) of the body (2) via interaction(s) of radiation entering and/or propagating within and/or exiting the body (2) with the said surface, and/or ii) modifying the directional distribution of radiation exiting and/or entering and/or propagating within the body (2) via the said surface, e.g. such as to reduce or ameliorate the deleterious effects of TIR within the body (2).

    摘要： A method of manufacturing laminate, comprising of at least two layers (1, 5) of thermoplastic materials with a diffractive optical element incorporated between them. In this method a layer (2) with a different refraction index from that of a carrying layer (1) and/or from that of a cover layer (5) of thermoplastic material is put on a carrying layer (1) and covered by the cover layer (5). The layer (2) with a different refraction index is placed only in some areas of the carrying layer (1). Subsequently a stamp (4) with optical diffractive relief (6) is imprinted and/or embossed into the layer (2) with a different refraction index. Then the cover layer (5) of thermoplastic material is put on the layer (2) with a different refraction index and the laminate is heated to a temperature at which bonding of the cover layer (5) and the carrying layer (1) occurs. A laminate, comprising of at least two layers (1, 5) of thermoplastic materials, with optical diffraction element incorporate between them.
