Converting a Lens to Its Equivalent as Referenced to Pupil Imaging

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.Keywords: Equivalent lens, Lens conversion, Pupil imaging, Optical system designOCIS codes: (080.2740) Geometric optical design; (080.3630) Lenses; (220.3620) Lens system design
