Title:
OPTICAL SYSTEM, IMAGE CAPTURING MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/279362
Kind Code:
A1
Abstract:
An optical system (100) comprises: a first lens (L1) having a positive refractive power and with an object-side surface (S1) being a convex surface and an image-side surface (S2) being a concave surface; a second lens (L2) having a refractive power and with an image-side surface (S4) being a concave surface; a third lens (L3) having a refractive power; a fourth lens (L4) having a positive refractive power and with an object-side surface (S7) thereof being a convex surface and an image-side surface (S8) being a convex surface; a fifth lens (L5) having a positive refractive power and with an object-side surface (S9) being a convex surface; a sixth lens (L6) having a negative refractive power and with an image-side surface (S12) being a concave surface; and the optical system (100) meets the following conditional expression: 10 ≤ (d12/f)*100 ≤ 22.5, wherein d12 is the distance, on an optical axis (110), between the image-side surface (S2) of the first lens (L1) and an object-side surface (S3) of the second lens (L2), and f is an effective focal length of the optical system (100).
