Hello everyone,


I am trying to design Digital Micromirror Device(DMD) in SEQ using 'us_mems.dll'. We know that the DMD behaves as a blazed grating, and also it has diffraction pattern, what I have seen during experiments also. I am wondering how can I simulate the diffraction orders of DMD in ZEMAX.

Thanks in advance.

Hi Ast,

The DMD model doesn't support a diffraction order parameter directly, so your best/only choice is to scale the pixel size instead.
