Hi! I have a perfectly working sequential model in OpticStudio, where I use “Elliptical grating 1” to model a reflective grating. I am desperately trying to recreate this in a non-sequential model, but can’t seem to get it working.

I am attempting to use the Binary 2A object. However, I only require one surface, not both sides, and the diffraction does not seem to be performing as expected. When I try to convert my sequential model to a non-sequential one using the Zemax wizard, it suggests a “Grid Sag Surface” and “Standard Surface” combined with a “Compound Lens”. However, this surface does not perform diffraction.

I tried to import the surface as a STEP file, but I also cannot get this to perform diffraction either.

Any guidance would be greatly appreciated. Thanks!

Hi Same question here,

When I follow this procedure I end up with a spherical component surface again. The boolean OR (+) makes it so that if I want the diffractive surface on the component, it needs to “stick out” and the sperical shape is then used again...


Hi,

Could you please provide more information how you add diffraction grating to a surface using Boolean  Native?. 

Thank you

 


For anyone looking, we did:

  1. Combine Biconic Surface with Standard Surface into a Compound Lens
  2. Combine Compound Lens with Rectangular Volume using Boolean Native (A&B)
  3. Combine Boolean Native with Diffraction Grating using Boolean Native (A+B)

This works in place of the Elliptical Grating 1.
