zebra:Code V 給的是垂軸像差,Zemax 給的是Seidel像差係數(shù)
兩者需要簡單轉(zhuǎn)換如下:
SA = S1 / (2n'u') : 3rd order spherical aberration
TCO = 3S2 / (2n'u& .. (2022-01-17 12:38)

Code V 給的是垂軸像差,Zemax 給的是Seidel像差係數(shù)
兩者需要簡單轉(zhuǎn)換如下: SA = S1 / (2n'u') : 3rd order spherical aberration TCO = 3S2 / (2n'u') : 3rd order tangential coma TAS = (3S3+S4) / (2n'u') : 3rd order tangential astigmatic blur SAS = ( S3+S4) / (2n'u') : 3rd order sagittal astigmatic blur PTB = S4 / (2n'u') : 3rd order Petzval blur DST = S5 / (2n'u') : 3rd order distortion SAbar= S6 / (2n'ub') : 3rd order pupil spheircal aberration dLFC = -CL / (n'u'^2) : Longitudinal chromatic aberration AX = CL / (n'u') : Axial transverse chromatic aberration LAT = CT / (n'u') : Transverse chromatic aberration PTZ = -S4 / H^2 : Petzval surface curvature 上式中: n'是像空間折射率 u'是邊緣光在像空間之傾斜角 H 是光學(xué)不變量 另外,不同軟體及書本對Seidel像差係數(shù)的定義可能差一負(fù)號,請小心。 |
