Abstract
(EN)
An optical system according to one embodiment of the present invention comprises a first lens, a second lens, a third lens, and a fourth lens that are sequentially arranged from an object side to an image side, and has an f value of 1.7 or less, wherein the ratio (TTL/f value) of the total top length (TTL) to the f value is 2.1 to 3.
(FR)
Un système optique selon un mode de réalisation de la présente invention comprend une première lentille, une deuxième lentille, une troisième lentille et une quatrième lentille qui sont agencées de manière séquentielle d'un côté objet à un côté image, et a une valeur f inférieure ou égale à 1,7, le rapport (valeur TTL/f) de la longueur supérieure totale (TTL) à la valeur f étant de 2,1 à 3.
(KO)
본 발명의 한 실시예에 따른 광학계는 물체(object)측으로부터 상(image)측으로 순차적으로 배열되는 제1 렌즈, 제2 렌즈, 제3 렌즈 및 제4 렌즈를 포함하고, f값이 1.7 이하이고, 상기 f값에 대한 TTL(Total Top Length)의 비(TTL/f값)가 2.1 내지 3이다.
