[0126] Please refer to Figure 1A and Figure 1B ,in Figure 1A A schematic diagram showing an imaging lens group according to a first embodiment of the present invention, Figure 1B From left to right are the spherical aberration, astigmatism and distortion curves of the imaging lens group of the first embodiment. Depend on Figure 1A It can be seen that the imaging lens group includes a diaphragm 100 and an optical group, and the optical group includes a first lens 110, a second lens 120, a third lens 130, a fourth lens 140, and a fifth lens 150 in sequence from the object side to the image side. , an infrared filter element 160 , and an imaging surface 170 , wherein there are five lenses with refractive power in the imaging lens group. The aperture 100 is disposed between the image-side surface 112 of the first lens 110 and the subject.
[0127] The first lens 110 has positive refractive power and is made of plastic material. Its object-side surface 111 is convex near the...
