Embodiment 1
[0096] Refer to the following Figure 1 to Figure 2 An optical imaging lens group according to Embodiment 1 of the present application is described. figure 1 A schematic structural diagram of an optical imaging lens group according to Embodiment 1 of the present application is shown.
[0097] Such as figure 1 As shown, the optical imaging lens group includes in sequence from the object side to the image side: the first lens E1, the second lens E2, the third lens E3, the fourth lens E4, the diaphragm STO, the fifth lens E5, and the sixth lens E6 , the seventh lens E7, the eighth lens E8, the filter E9 and the imaging surface S19.
[0098] The first lens E1 has negative refractive power in the Y-axis direction of the optical imaging lens group, and has negative refractive power in the X-axis direction of the optical imaging lens group. The object side S1 is convex, and the image side S2 is concave. The second lens E2 has positive refractive power in the Y-axis direction of the ...
