Patent ID: 8339715

Claim:
A three-piece optical pickup lens comprising, sequentially from an object side to an image side of the three-piece optical pickup lens along an optical axis thereof: an aperture stop; a first lens being a meniscus lens of positive refractive power; a second lens having an object side and an image side; and the object side and the image side respectively having at least one inflection point located at a position between a center and a periphery of the second lens; and a third lens having an object side and an image side and having positive refractive power at paraxial region of optical axis; and the object side and the image side respectively having at least one inflection point located at a position between a center and a periphery of the third lens; wherein the three-piece optical pickup lens satisfies the following condition: 1.21 ≦f 1 /f≦ 1.66 −2.40 ≦f 2 /f≦ 6.34 0.81 ≦f 3 /f≦ 2.95 where, f is an effective focal length of the three-piece optical pickup lens; f 1 is an effective focal length of the first lens; f 2 is an effective focal length of the second lens; and f 3 is an effective focal length of the third lens.
