Abstract

The equivalent of a thick lens is a lens which has the same power of refraction and paraxial imaging characteristics for a reference ray, but with a different axial thickness. In this study, thick lenses of an optical system were converted to their equivalent lenses referenced to pupil imaging. Aberration changes due to the lens conversion were compared to the general equivalent lens conversion referenced to object imaging.

등가렌즈는 굴절능과 특정한 기준광선에 대한 근축광학적 특성은 같고, 축상두께가 다른 렌즈이다. 이 연구에서는 동의 결상을 기준으로 광학계의 두꺼운 렌즈를 등가렌즈로 변환하고 일반적으로 사용되던 물체의 결상을 기준으로 등가렌즈로 변환한 경우와 Seidel 수차의 변화를 비교하였다.
