Abstract: Provided are a composite photosensitive element and a method for preparing a composite photosensitive element, and the composite photosensitive element includes a photosensitive element and a near-infrared absorption layer pasted on the photosensitive element, wherein the near-infrared absorption layer includes a copper complex, and the copper complex is formed from a copper compound providing copper ions, phosphoric acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein, wherein the OD value of the near-infrared absorption layer for the incident light wavelength from 930-950 nm is greater than 4. The present disclosure forms a filtering film directly on the photosensitive element instead of using a traditional filter assembly to reduce the size of the assembled product. The filtering film can be further processed and shaped to have functions of micro-lens.

Abstract: Provided is a filter lens and a method for preparing the filter lens. The filter lens includes a copper complex, wherein the copper complex is formed from a copper compound providing copper ions, phosphoric acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein, wherein the OD value of the filter lens for the incident light wavelength of 930 nm to 950 nm is greater than 4. The present disclosure enables a filter lens to have the function of filtering out near-infrared instead of using a traditional filter component and thus the size of the assembled optical lens module is reduced. The filter lens can further filter out light having other specific wavelengths, and thereby the number of lenses in the assembled optical lens module is reduced.

Abstract: Provided is a filter, including a substrate layer and a near-infrared absorption layer on the substrate layer, wherein the near-infrared absorption layer includes a copper complex formed from a copper compound for supplying copper ion, phosphonric acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein, wherein the OD value of the filter for the incident light wavelength from 930-950 nm is greater than 4. In the present disclosure, by setting a specific near-infrared absorption layer on the filter, the filter is able to efficiently absorb near-infrared and exhibit excellent visible light transmittance, and the burden of film post-processing can be reduced.

Abstract: Provided is an ultraviolet-absorbing resin composition, including 35 to 45 wt % of a fluorocarbon resin, 5 to 25 wt % of an isocyanate curing agent, 1 to 5 wt % of an ultraviolet absorbent, and a residual solvent accounting for the balance, based on the total weight of the ultraviolet-absorbing resin composition. Provided is also an ultraviolet-absorbing resin, an ultraviolet-absorbing structure including the same, and the method for preparing the same. The present disclosure obtains an ultraviolet-absorbing resin with a specific composition from a specific resin composition formula, and the ultraviolet-absorbing resin efficiently absorbs ultraviolet and has excellent visible light transmittance, as well as high stability.

Abstract: Provided is a lens module with an integrated structure, including a first lens and a second lens, a first substrate and a second substrate, an optical bonding layer, a first absorption layer and a second absorption layer, wherein the first absorption layer includes a copper complex, which is formed from a copper compound, a phosphonic acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein. Due to the integrated structure, the lens module can be reduced in size. The manufacturing process is simplified because no assembly process is required. The lens module of the present disclosure exhibits high transmittance for visible light and low transmittance for near-infrared, showing an excellent near-infrared cut-off effect. In addition, while the incident light irradiates the lens module at different angles, the transmittance curve only is slightly shifted.
