  • Publication number: 20180120451
    Abstract: 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.

  • Patent number: 9482803
    Abstract: A holographic sight is provided having a housing that includes a plurality of holograph sight components. A laser diode mounted in the housing is configured to emit a laser light beam. The light beam is transmitted to an integrated diffraction grating and filter unit which includes a grating and a filter in a single device. The diffraction grating has a grating surface for diffracting the light beam and also diffracting unwanted ambient light transmitted into the housing. The filter is an optical filter contacting at least a portion of the grating. The optical filter is adapted to absorb at least one wavelength of the ambient light to inhibit the ambient light from diffracting into a visible spectrum that might otherwise be viewable to a user looking into the holographic sight.

  • Publication number: 20150285967
    Abstract: Optical components and systems comprising combined optical filters and diffraction gratings are generally described. In certain embodiments, an optical filter is in contact with a diffraction grating. In certain embodiments, the optical filter and the diffraction grating can be used to diffract and direct a first portion of electromagnetic radiation incident upon the grating and filter toward a receiver while filtering a second portion of the electromagnetic radiation incident upon the grating and filter.

  • Publication number: 20090091834
    Abstract: The invention discloses a diffractive device and a method of creating the same displaying a three-dimensional preferably achromatic image, especially imitating a real or an imaginary relief scene, a flat microrelief or otherwise modulated structure (10) of a diffractive type is created, the structure (10) comprising system of diffraction zones (5) which are arranged so that in places of diffractive structure (10) corresponding to places of the relief scene (11) the diffraction zones (5) have such periodicity and orientation (a, b) that cause deflection of incident light (9) in the same direction as the relief scene (11) deflects an incident light, thus achieving a visible thee-dimensional and largely achromatic sensation of image, corresponding to the relief scene (11), when observing the diffractive structure (10) regardless of conditions of lighting.
