Abstract:
An optical image lens assembly includes a plurality of optical lens elements, wherein the optical lens elements include a plurality of plastic optical lens elements having refractive power and aspheric surfaces. Wherein at least one long-wavelength red light absorbing optical lens element made of a plastic material and having refractive powers is disposed within the optical image lens assembly, and the long-wavelength red light absorbing optical lens element can be penetrated by a visible light and can filter a long-wavelength red light.
