| Zusammenfassung: | An imaging optical system of the present invention includes: a first prism configured to emit light incident along a first optical axis in a direction of a second optical axis crossing the first optical axis; a first lens having a convex image side surface; a second lens having a concave image side surface; a third lens having refractive power; and a fourth lens having a convex shape on the object side, wherein the first prism, the first lens, the second lens, the third lens, and the fourth lens are sequentially disposed along the second optical axis direction. An objective of the present invention is to provide the imaging optical system that can be mounted on a thin portable terminal while having a long focal length.
본 발명의 촬상 광학계는 제1광축을 따라 입사되는 빛을 상기 제1광축과 교차하는 제2광축 방향으로 출사시키도록 구성되는 제1프리즘; 상 측면이 볼록한 형상인 제1렌즈; 상 측면이 오목한 형상인 제2렌즈; 굴절력을 갖는 제3렌즈; 및 물체 측면이 볼록한 형상인 제4렌즈;를 포함하고, 상기 제1프리즘, 상기 제1렌즈, 상기 제2렌즈, 상기 제3렌즈, 및 상기 제4렌즈는 상기 제2광축 방향을 따라서 순차적으로 배치된다. |
