【摘要】 本文提出,赛得（Seidel）象差理论存在两个前提:在光学系统中对确定的物面,1)入瞳座标表示孔径;2)孔径相同,球差（S₁、S₁…）相同。这两个前提同时成立的范围就是赛得象差理论的应用范围。本文证明:这个范围仅包括光学系统的小视场。更多还原

【Abstract】 Two prerequisites of Seidel Aaberration theory are proposed for a fixed objecs plane in optical system.1.Aperture is expressed by coordinate of entrance pucil.2.Spherical aberrations（S₁,S₁¹……）are equal to each other as aperturehave the same dimension.Then the application range of Seidel aberration theory is just the scale inwhich the above-mentioned prerequisites exist.It is proved that this range onlyinclude the small field of optic system.更多还原
