  • Patent number: 10473837
    Abstract: An optical interference coating with reduced back reflectance for 3D glasses based on colour separation has a substantial transmittance at one or more passbands over the visible spectral range in order to view the desired left (right) eye image and a substantial reflectance and absorption at one or more different blocking bands over the visible spectral range in order to block the undesired right (left) eye image while simultaneously reducing the back reflectance of visible light towards the viewer's eye. The thicknesses and materials are chosen such that the left eye reduced back reflectance 3D coated lens transmits the desired left eye image and blocks the right eye image while the right eye reduced back reflectance 3D coated lens transmits the desired right eye image and blocks the left eye image so that a 3D image can be viewed whilst substantially reducing distracting back reflections from the coated lenses.

  • Patent number: 10392276
    Abstract: The present invention provides a TiO2-based coagulant and use thereof. The TiO2-based coagulant is obtained by the following steps: uniformly mixing acetylacetone and ethanol and dropwise adding titanium tetrachloride to obtain a solution A; mixing deionized water and ethanol to obtain a solution B; dropwise adding solution B to solution A; stirring to obtain a sol, and then aging the sol to constant weight to obtain the TiO2-based coagulant. The TiO2-based coagulant can be used for treating waste water and algae-laden water. The TiO2-based coagulant exhibits good coagulation effects and high stability, solves the problem of too low effluent pH caused by strong inorganic titanate acidity and is favorable to the subsequent treatment of waste water.

  • Patent number: 10358865
    Abstract: Certain example embodiments of this invention relate to articles including anticondensation and/or low-E coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anti condensation and/or low-E coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator/freezer doors, and/or the like.

  • Patent number: 10317591
    Abstract: The present invention discloses a coated narrow-band filter having an absorbent material. Two sides of the substrate are respectively an A-side and a B-side, a cut-off layer is coated or screen printed on the A-side, wherein lights having a wavelength within a first band are allowed to pass through the cut-off layer. The substrate is an absorbent layer, or an absorbent layer is provided on the B-side of the substrate. The absorbent layer is made of an absorbent material, lights having a wavelength within a second band are allowed to pass through the absorbent layer. The first band partially overlaps with the second band. For processing convenience, the coated narrow-band filter having an absorbent material is provided at different angles and with small angle of incidence.
