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.
Claims27
An optical image lens assembly, comprising:
- a plurality of optical lens elements, wherein the optical lens elements comprise 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 power is disposed in 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;
- wherein a transmitted distance of a chief ray passing through the long-wavelength red light absorbing optical lens element between a central field of view to a field of view in 1.0 region in an imaging region of the optical image lens assembly is CP, a transmitted distance of the chief ray passing through the long-wavelength red light absorbing optical lens element in the central field of the optical image lens assembly is CP0, and the following condition is satisfied:
- 0.5≤CP/CP0≤2.0.
