초록

낮은 NA의 굴절형 대물렌즈와 반사형 focal reducer로 구성된 NA 0.5의 굴절-반사 대물렌즈를 설계하였다. 굴절형 대물렌즈로는 NA 0.25인 Lister 대물렌즈가 사용되고, 반사형 focal reducer는 구면수차, 코마, 비점수차가 보정된 2구면경계가 사용되었다. 설계된 굴절-반사 대물렌즈는 높은 NA를 가졌음에도 18 mm의 긴 작동거리와 NA 0.25의 Lister 대물렌즈보다 개선된 결상성능을 가지고 있다.

A 0.5-numerical-aperture (NA) refractive-reflective objective, composed of a low-NA refractive and a reflective focal reducer, is designed. A 0.25-NA Lister objective is used for the refractive. A two-spherical-mirror system, corrected for spherical aberration, coma, and astigmatism is used for the reflective focal reducer. In spite of high NA, the refractive-reflective objective has an 18-mm working distance and improved imaging performance, compared to the 0.25-NA Lister objective.
