[0032] Referring to the accompanying drawings, the present invention provides an imaging optical lens 10 . figure 1 Shown is the imaging optical lens 10 of the first embodiment of the present invention, and the imaging optical lens 10 includes six lenses. Specifically, the imaging optical lens 10 includes, from the object side to the image side in sequence: an aperture S1, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, and a sixth lens. Lens L6. In this embodiment, preferably, an optical element such as a glass plate GF is arranged between the sixth lens L6 and the image plane Si, wherein the glass plate GF can be a glass cover, or an optical filter (filter). In other possible implementation manners, the glass plate GF can also be arranged at other positions.
[0033] In this embodiment, the first lens L1 has a positive refractive power, its object side is convex outward, and its image side is concave; the second lens L2 has negative r...
