Title:
OPTICAL LENS, IMAGE ACQUISITION DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/016149
Kind Code:
A1
Abstract:
An optical lens, an image acquisition device (200) and an electronic device (300). The optical lens at least comprises, along an optical axis from an object side to an image side, a first lens (L3) having a positive refractive power, a second lens (L4) having a negative refractive power, a third lens (L5) having a positive refractive power, a fourth lens (L6) having a negative refractive power, and a phase plate (L2).The tangent value of half of the maximum field of view (HFOV) of the optical lens, and the optical axis distance from the object side surface of the optical element which is closest to the object side of the optical lens and having refractive power to the imaging surface (S15) of the optical lens satisfy the condition: 0.15 mm − 1 ≤|tan (HFOV)|/TTL ≤ 0.35 mm − 1, and the effective focal length f of the optical lens and the effective focal length f2 of the second lens (L4) satisfy the condition: − 40 ≤ f2/f ≤ − 10.
