zemax源码： This DLL models an anamorphic aspheric surface. This surface is essentially an even aspheric surface with different terms for the x and y directions. The sag is given by: Z = ((CX*x*x)+(CY*y*y)) / (1 + sqrt(1-((1+KX)*CX*CX*x*x)-((1+KY)*CY*CY*y*y))) + AR*( (1 - AP)*x*x + (1 + AP)*y*y )^2 + BR*( (1 - BP)*x*x + (1 + BP)*y*y )^3 + CR*( (1 - CP)*x*x + (1 + CP)*y*y )^4 + DR*( (1 - DP)*x*x + (1 + DP)*y*y )^5 Note the terms AR, BR, CR, and DR ... have units of length to the -3, -5, -7, and -9 power. The terms AP, BP, CP, and DP are dimensionless. The surface is rotationally symmetric only if AP = BP = CP = DP == 0 and CX = CY and KX = KY. -ZEMAX source: This DLL models an anamorphic aspheric surface.This surface is essentially an even aspheric surface with different terms forthe x and y directions.The sag is given by: Z = ((CX* x* x)+ (CY* y* y))/(1+ sqrt (1- ((1+ KX)* CX* CX* x* x)- ((1+ KY)* CY* CY* y* y)))+ AR* ((1- AP)* x* x+ (1+ AP)*
