Embodiment 1
[0077] Refer to the following Figure 1 to Figure 2D The optical imaging lens according to Embodiment 1 of the present application is described. figure 1 A schematic structural diagram of the optical imaging lens according to Embodiment 1 of the present application is shown.
[0078] like figure 1 As shown, the optical imaging lens includes sequentially from the object side to the image side along the optical axis: a first lens E1, a second lens E2, a diaphragm STO, a third lens E3, a fourth lens E4, a fifth lens E5, a sixth lens Lens E6, seventh lens E7 and filter E8.
[0079] The first lens E1 has negative refractive power, the object side S1 is convex, and the image side S2 is concave. The second lens E2 has positive refractive power, the object side S3 is concave, and the image side S4 is convex. The third lens E3 has positive refractive power, the object side S5 is convex, and the image side S6 is convex. The fourth lens E4 has negative refractive power, the object s...
Embodiment 2
