Abstract

본 발명은 캠코더나 스틸카메라 등과 같은 촬영기기의 광학계를 개시한다. 개시된 광학계는, 복수개의 렌즈와, 상기 복수개의 렌즈사이에 설치되며 그 중심부로 부터 가장자리로 갈수록 투과율이 순차적으로 감소되도록 구획된 순차차광막을 구비하여 구성된다. 따라서 축외수차를 극소화 시킬수 있어 고품질의 화상을 얻을수 있으며,구조가 간단하여 콤팩트화가 가능함과 동시에 단가를 낮출 수 있게 된다.The present invention discloses an optical system of a photographing apparatus such as a camcorder or a still camera. The disclosed optical system includes a plurality of lenses and a sequential light shielding film provided between the plurality of lenses and partitioned so that the transmittance is sequentially reduced from the center to the edge. Therefore, the axial aberration can be minimized to obtain a high quality image, and the structure is simple, so that the compactness and the unit cost can be reduced.
