光学设计软件zemax源码: This DLL models an nular aspheric surface as described in: "annular surfaces in annular field systems" By Jose M. Sasian Opt. eng. 36 (12) P 3401-3401 December 1997 This surface is essentially an odd aspheric surface with an offset in the aspheric terms. The sag is given by: Z = (c*r*r) / (1+(1-((1+k)*c*c*r*r))^ 1/2 ) + a*(r-q)^2 + b*(r-q)^3 + c*(r-q)^4 + ... Note the terms a, b, c, ... have units of length to the -1, -2, -3, ... power.

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.
