Code V 給的是垂軸像差,Zemax 給的是Seidel像差係數 tE9%;8;H
兩者需要簡單轉換如下: i~n>dc YW
5=.,a5
SA = S1 / (2n'u') : 3rd order spherical aberration _Wk!d3bsx
TCO = 3S2 / (2n'u') : 3rd order tangential coma !R[o6V5T
TAS = (3S3+S4) / (2n'u') : 3rd order tangential astigmatic blur <{3VK
SAS = ( S3+S4) / (2n'u') : 3rd order sagittal astigmatic blur 'd|_ i6:y&
PTB = S4 / (2n'u') : 3rd order Petzval blur (lwkg8WC

n'是像空間折射率 )`,3/i9C$
u'是邊緣光在像空間之傾斜角 @Ej{sC!0T
H 是光學不變量 nr!kx)j

另外,不同軟體及書本對Seidel像差係數的定義可能差一負號,請小心。
