Abstract
The present disclosure discloses an optical imaging system including, sequentially from an object side to an image side along an optical axis, a first lens having a negative refractive power, and an image-side surface thereof being concave; a second lens having a refractive power; a third lens having a positive refractive power, and an object-side surface thereof being convex and an image-side surface thereof being convex; a fourth lens having a negative refractive power; a fifth lens having a refractive power, and an image-side surface thereof being convex; and a sixth lens having a refractive power, wherein half of a maximum field-of-view Semi-FOV of the optical imaging system satisfies Semi-FOV>60°; and a maximum effective radius DT12 of the image-side surface of the first lens and a maximum effective radius DT62 of an image-side surface of the sixth lens satisfy 0.5<DT12/DT62<1.
