Abstract
겸용교환렌즈용 수차보정판은 촬상장치의 전면에 구비된 커다란 결과의 필터 두께를 갖는 제 1 카메라 몸체 및 겸용교환렌즈가 제 2 카메라 몸체에 장착될때 겸용교환렌즈의 후단에 장착된 촬상장치의 전면에 구비된 작은 결과의 필터두께를 갖는 제 2 카메라몸체에 분리가능하게 부착가능하다. 수착보정판은 굴절율(N)이 1.7보다 큰 평행판 혹은 부의 파워의 렌즈로 만들어진다. 수차보정판의 두께 및 제 2 카메라 몸체의 촬상장치의 전면에 구비된 필터의 두께의 합은 실질적으로 제 1 카메라 몸체의 촬상장치의 전면에 구비된 필터의 총 두께보다 작거나 동일하다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도는 본 발명의 제 1 실시예에 따른, 컬러/흑백 영상의 겸용교환렌즈에 장착되는 수차보정판을 포함하는 광학시스템의 개략도, 제 3 도는 겸용교환렌즈의 상반부가 절단되고, 그 후단에 장착된 제 1 도에 도시된 수차보정판의 측면도, 제 4 도는 흑백 카메라 몸체에 부착되는 제 3 도에 도시된 겸용교환렌즈의 상부의 절반의 단면도.
Claims (1)
- 제 1 카메라 몸체의 촬상장치의 전면에 구비된 필터의 커다란 합성두께를 갖는 제 1 카메라 몸체 및 제 2 카메라 몸체의 촬상장치의 전면에 구비된 필터의 작은 합성두께를 갖는 제 2 카메라 몸체에 분리가능하게 부착되어질수 있는 겸용교환용 수차보정판으로서, 상기 수차보정판은 겸용교환렌즈가 제 2 카메라 몸체에 장착될때 겸용교환렌즈의 후단에 장착되어지며, 상기 수차보정판은 굴절률(N)이 1.7보다 큰 (1.7〈N) 평행-판으로 만들어지며, 수차보정판의 두께와 제 2 카메라 몸체의 촬상장치의 전면에 구비된 필터의 두께의 합이 실질적으로 제 1 카메라 몸체의 촬상장치의 전면에 구비된 필터의 총두께와 동일한 것을 특징으로 하는 수차보정판.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
