Hello, ZEMAX user
I want to roughen the surface of the lens.
I want to generate scattered reflection rather than regular reflection.
How do I set it up?
Can't I see the light scattered by the reflector through NSC 3D Layout?
Thank you

Hi Suhwan,
First, you'll want to set the properties on your NSC object to scatter light with a particular scatter profile. If you need help on this, let me know.
Once you have your object properties set to scatter, then you'll want to enable polarization and scattering in both your raytrace settings as well as your layout plot settings. Note that layout and raytracing settings are handled separately! That one tricks quite a few people.
Finally, depending on how your system is configured, you may also want to enable ray splitting in both places. Ray splitting allows one ray to take both the reflected and the transmitted path (with energy divided between the two paths) when it encounters an optical interface. If you want all the light to take the reflected path, then you can turn off ray splitting and give your object a 'MIRROR' material.

Hi Alissa Wilczynski
I figured out how to see the scattered rays.
And I learned how to raytrace the scattered rays.
Thank you very much.
