Open the included Beam_Homogenizer.ZMX lens file.

 

The sample system is a single plano-convex lens with an Even Aspheric front surface. The variables are radius, conic and the even aspheric coefficients. The system wavelength is 0.623 um (HeNe) and the glass type is N-BK7.



In the main menu, click Macros/Beam Homogenizer.

 

After executing the macro, the layout window will look like this.



Notice that the input ray apodization is Gaussian but the output is uniform. The spacing between the rays at the image surface is very uniform indicating that the irradiance distribution should be close to ideal Top Hat.
