Title:
PHOTOGRAPHING OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/097927
Kind Code:
A1
Abstract:
Provided is a photographing optical lens, sequentially comprising, from an object side to an image side, a first lens with a negative refraction power, a second lens with a positive refraction power, a third lens with a negative refraction power, a fourth lens with a positive refraction power, and a fifth lens with a negative refraction power, satisfying the following relational expressions: -6.00 ≤ f1/f ≤ -3.00, 1.80 ≤ (f2+f4)/f ≤ 2.50, 1.00 ≤ d2/d1 ≤ 2.00, and 5.00 ≤ (R5+R6)/(R5-R6) ≤ 15.00. The photographing optical lens satisfies the requirements of a large-aperture, wide-angle and ultra-thin design while exhibiting a good optical performance.
