Embodiment 1
[0091] Refer to the following Figure 1 to Figure 2D An optical imaging lens according to Embodiment 1 of the present application is described. figure 1 A schematic structural diagram of an optical imaging lens according to Embodiment 1 of the present application is shown.
[0092] like figure 1As shown, the optical imaging lens includes in sequence from the object side to the image side along the optical axis: the first lens E1, the diaphragm STO, the second lens E2, the third lens E3, the fourth lens E4, the fifth lens E5, the sixth lens Lens E6, seventh lens E7 and filter E8.
[0093] The first lens E1 has negative refractive power, its object side S1 is convex, and its image side S2 is concave. The second lens E2 has positive refractive power, its object side S3 is convex, and its image side S4 is convex. The third lens E3 has negative refractive power, its object side S5 is convex, and its image side S6 is concave. The fourth lens E4 has positive refractive power, it...
