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)* 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 2B ! DP)* y* y) ^ 5Note 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.
