Document Type and Number:
WIPO Patent Application WO/2022/109820
Kind Code:
A1
Abstract:
An optical system (10) comprises: a first lens (L1) having positive refractive power; a second lens (L2) having negative refractive power; a third lens (L3) having positive refractive power; a fourth lens (L4) having an object-side surface (S7) being concave in a paraxial region thereof and an image-side surface (S8) being convex in a paraxial region thereof; a fifth lens (L5) having positive refractive power, an aspheric object-side surface (S9) and an aspheric image-side surface (S10); and a sixth lens (L6) having negative refractive power, an aspheric object-side surface (S11) and an aspheric image-side surface (S12), at least one of the object-side surface (S11) and the image-side surface (S12) being provided with an inflection point. The system satisfies the following relationship: 0.25 < SD11/ImgH < 0.35, wherein SD11 is the maximum effective radius of an object-side surface (S1) of the first lens (L1), and ImgH is half of the image height corresponding to the maximum field of view of the optical system (10).
