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: The present technology relates to a solid-state imaging device, an imaging apparatus, and an electronic apparatus, which can suppress a color mixture without lowering the sensitivity.
In pixels (red pixels (R pixels), green pixels (G pixels), and blue pixels (B pixels)) other than W pixels and adjacent to the W pixels, light shielding films thicker than those of the W pixels are formed at positions adjacent to the W pixels. Furthermore, the shorter the wavelength, the thicker the light shielding film in the RGB pixels other than the W pixels. The present technology is applicable to the solid-state imaging device.-

Abstract: An infrared filter film layer and an infrared filter structure are provided. The infrared filter film layer includes at least one silicon-based layer, at least one isolation layer, and at least one oxide layer that are stacked with each other. The at least one isolation layer is disposed between the at least one silicon-based layer and the at least one oxide layer. Through this configuration, the infrared filter film layer has good quality, such that an amount of wavelength drift is small in application. The infrared filter structure includes a light-transmitting substrate and the infrared filter film layer.

Abstract: A protective lens stack comprises a base layer including a polyethylene terephthalate (PET) film containing a UV blocking additive and one or more removable lens layers stacked on top of the base layer. Each of the removable lens layers may include a PET film and a first adhesive disposed on a bottom surface of the PET film. Refractive indices of the base layer and the one or more removable lens layers may be matched to within 0.2. Each layer of the protective lens stack, including the base layer and each of the removable lens layer(s), may have less than 0.5% haze. The protective lens stack may be used as a face shield or may be surface mountable using a second adhesive disposed on a bottom surface of the PET film containing the UV blocking additive.
