More Information
Summary:An imaging optical system of the present invention comprises: a first lens having negative refractive power; a second lens having positive refractive power; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having positive refractive power; a sixth lens having negative refractive power and having a convex shape on an object side; and a seventh lens having refractive power and having an inflection point formed on an image side. Thus, the present invention can provide the imaging optical system with a short overall length. 본 발명의 촬상 광학계는 부의 굴절력을 갖는 제1렌즈; 정의 굴절력을 갖는 제2렌즈; 굴절력을 갖는 제3렌즈; 굴절력을 갖는 제4렌즈; 정의 굴절력을 갖는 제5렌즈; 부의 굴절력을 가지며, 물체 측면이 볼록한 형상인 제6렌즈; 및 굴절력을 가지며, 상 측면에 변곡점이 형성되는 제7렌즈;를 포함한다.
