Building a diffuser in Zemax OpticStudio involves creating a surface or object that scatters or diffuses light. Here's a general guide on how to create a diffuser in Zemax OpticStudio:

Go to the Non-Sequential Mode (NSC) tab. NSC is useful for modeling non-sequential rays that interact with objects rather than surfaces.

Create a new object where you want the diffuser. Objects can be 2D or 3D shapes. Specify the shape, size, and position of the object. Define Material Properties.

To make the surface or object act as a diffuser, specify its scattering properties. This can be done using the "Scatter" property. Set the scattering characteristics, depending on whether you're using a surface or an object-based diffuser.

Specify the scattering angle distribution, scattering efficiency, and other relevant parameters based on the type of diffuser you want to create. The choice of these parameters will depend on the specific characteristics of your diffuser.

Then configure your ray tracing settings to analyze the performance of the diffuser. You may want to use a source that emits rays at various angles and positions to see how the diffuser scatters light.
