Abstract[English]
A photographing optical lens (10, 20, 30, 40, 50), sequentially comprising, from an object side to an image side: a first lens (L1) having positive refractive power, a second lens (L2) having refractive power, a third lens (L3) having positive refractive power, and a fourth lens (L4) having negative refractive power. The following relational expressions are satisfied: 0.15≤d6/TTL≤0.25; 0.80≤f1/f≤0.95; 0.97≤TTL/f≤1.20; 4.00≤(R5+R6)/(R5-R6)≤60.00; and 0.30≤d3/d5≤1.20.[French]
Un objectif optique de photographie (10, 20, 30, 40, 50), comprenant séquentiellement, d'un côté objet vers un côté image : une première lentille (L1) ayant une réfringence positive, une deuxième lentille (L2) ayant une réfringence, une troisième lentille (L3) ayant une réfringence positive, et une quatrième lentille (L4) ayant une réfringence négative. Les expressions relationnelles suivantes sont satisfaites : 0.15≤d6/TTL≤0.25 ; 0.80≤f1/f≤0.95 ; 0.97≤TTL/f≤1.20 ; 4.00≤(R5+R6)/(R5-R6)≤60.00 ; et 0.30≤d3/d5≤1.20.[Chinese]
一种摄像光学镜头（10，20，30，40，50），自物侧至像侧依序包含：具有正屈折力的第一透镜（L1），具有屈折力的第二透镜（L2），具有正屈折力的第三透镜（L3），具有负屈折力的第四透镜（L4）；且满足下列关系式：0.15≤d6/TTL≤0.25；0.80≤f1/f≤0.95；0.97≤TTL/f≤1.20；4.00≤(R5+R6)/(R5-R6)≤60.00；0.30≤d3/d5≤1.20。
