Example Embodiment
[0081] Example 1
[0082] The following reference figure 1 with figure 2 The imaging lens according to Embodiment 1 of the present application is described. figure 1 A schematic structural diagram of an imaging lens according to Embodiment 1 of the present application is shown.
[0083] Such as figure 1 As shown, the imaging lens according to the exemplary embodiment of the present application includes in order from the object side to the image side along the optical axis: a stop STO, a first lens E1, a second lens E2, a third lens E3, a fourth lens E4, The fifth lens E5, the filter E6 and the imaging surface S13.
[0084] The first lens E1 has a positive refractive power, the object side surface S1 is convex, and the image side surface S2 is convex. The second lens E2 has negative refractive power, the object side surface S3 is a convex surface, and the image side surface S4 is a concave surface. The third lens E3 has a positive refractive power, the object side surface S5 is a ...
