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.
