Description
Claims (5)
- 대물렌즈와, 릴레이렌즈부를 포함하여 이루어지는 내시경 광학계에 있어서,상기 릴레이렌즈부의 내측에는 릴레이렌즈부의 렌즈와 렌즈 사이에 형성되거나, 마지막 렌즈의 일측에 형성되어 조명광을 반사 및 투과하는 빔 스플리터를 형성하고, 조명광을 조명위치까지 전달하는 광학부품을 글라스로드로 형성하여 조명광이 광학계 내부에서 광축과 동축으로 진행하도록 하는 것을 특징으로 하는 동축조명 내시경 광학계.
- 청구항 1에 있어서, 상기 릴레이렌즈부의 마지막 렌즈의 일측단부와 측부로는 결상위치와, 조명위치가 형성되고, 상기 조명위치는 조명영역을 촬영하고자 하는 촬영대상물체의 영역보다 크게 하기 위하여 상기 결상위치의 크기보다 크기를 크게 형성하고, 위치를 가깝거나 멀게 형성한 것을 특징으로 하는 동축조명 내시경 광학계.
- 삭제
- 청구항 2에 있어서, 상기 조명위치는 광원으로부터 출사되는 조명광이 결상되는 위치인 것을 특징으로 하는 동축조명 내시경 광학계.
- 삭제
