[0040] 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. exist figure 1 Among them, the left side is the object side, and the right side is the image side. The photographic optical lens 10 includes six lenses in total, and from the object side to the image side are the first lens L1, the aperture S1, the second lens L2, the third lens L3, The fourth lens L4, the fifth lens L5 and the sixth lens L6. An optical element such as an optical filter (filter) GF may be disposed between the sixth lens L6 and the image plane Si.
[0041]In this embodiment, the first lens L1 is made of glass, the second lens L2 is made of plastic, the third lens L3 is made of glass, the fourth lens L4 is made of plastic, the fifth lens L5 is made of plastic, and the sixth lens L6 Made of plastic. In other embodiments, each lens can also be made of other mat...
