zemax的固有模式的优化:
依旧以(3)中的双胶合为例子介绍:
分析:双胶合公共有3个R变量,2个厚度,2个玻璃材料,因为没有空气间隙,其实双胶合类似于单片,从相差来看,厚度并不是主要因素,因此只将3个
R以及两个玻璃材料作为变量;边缘厚度如果影响成像质量时合理加厚玻璃即可;玻璃材料直接将玻璃库锁定在设定的库中即可。
注意上述表现需要重新变换玻璃库,代码如下:
function [r] = BeginApplication(TheApplication, args)
import ZOSAPI.*;
% creates a new API directory
TheSystem = TheApplication.PrimarySystem;
% Add your custom code here...
% 加载一下系统
b_load=TheSystem.LoadFile(System.String.Concat( 'C:\Users\admin\Desktop\matlabtest\LENS.zmx'), false);
% 系统LDE
TheLDE = TheSystem.LDE;
%Add 3 wavelengths: F,d,C
SystExplorer = TheSystem.SystemData;
slPreset = SystExplorer.Wavelengths.SelectWavelengthPreset(ZOSAPI.SystemData.WavelengthPreset.FdC_Visible);
% 设置变量
% 定义面
Surface_1 = TheLDE.GetSurfaceAt(1);
Surface_2 = TheLDE.GetSurfaceAt(2);
Surface_3 = TheLDE.GetSurfaceAt(3);
% 曲率为变量
Solver_V_1 = Surface_1.RadiusCell.CreateSolveType(ZOSAPI.Editors.SolveType.Variable);
Solver_V_2 = Surface_2.RadiusCell.CreateSolveType(ZOSAPI.Editors.SolveType.Variable);
Solver_V_3 = Surface_3.RadiusCell.CreateSolveType(ZOSAPI.Editors.SolveType.Variable);
Surface_1.RadiusCell.SetSolveData(Solver_V_1);
Surface_2.RadiusCell.SetSolveData(Solver_V_2);
Surface_3.RadiusCell.SetSolveData(Solver_V_3);
% 最后一个面厚度为变量
Solver_T_3 = Surface_3.ThicknessCell.CreateSolveType(ZOSAPI.Editors.SolveType.Variable);
Surface_3.ThicknessCell.SetSolveData(Solver_T_3);
% 玻璃设置为替代
Solver_M_1 = Surface_1.MaterialCell.CreateSolveType(ZOSAPI.Editors.SolveType.MaterialSubstitute );
Solver_M_2 = Surface_2.MaterialCell.CreateSolveType(ZOSAPI.Editors.SolveType.MaterialSubstitute );
Surface_1.MaterialCell.SetSolveData(Solver_M_1);
Surface_2.MaterialCell.SetSolveData(Solver_M_2);
% 直接照搬例子即可

上述代码未进行换玻璃计算,下一步进行换玻璃。
