Title:
OPTICAL SYSTEM, CAMERA MODULE AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/072668
Kind Code:
A1
Abstract:
An optical system (100), comprising the following in sequence from the object side to the image side: a first lens (L1) having positive refractive power; a second lens (L2) having negative refractive power; a third lens (L3) having negative refractive power; a fourth lens (L4) having negative refractive power; a fifth lens (L5) having negative refractive power; and a sixth lens (L6) having positive refractive power. Moreover, the optical system (100) satisfies the relationship: 0.51≤TLENS/TTL≤0.71, wherein TLENS is the distance on the optical axis from an object side surface (S1) of the first lens (L1) to an image side surface (S12) of the sixth lens (L6), and TTL is the total optical length of the optical system (100).
