Hi All,

 

Is there a simple way to model a cylindrical fresnel lens in NSC mode?

Didn’t find anything in the knowledge base.

 

Thanks,

Nadav

Hi,

You can use either a Fresnel 1 or Fresnel 2 object to model a cylindrical Fresnel lens. Fresnel 1 has real sag profile and Fresnel 2 is idealised.
