I have a LED as object surface (±1mm object height) and 2mm thick Diffuser (ground glass) about 5mm away from OBJ surface. The Diffuser Surface 2 is ground glass surface with a Lambertian scatter property. I would like this surface to be the actual object surface that I can image onto to image plane. How could I model this sequentially in zemax?

A schematic illustration of what I intend to design:

Hi Asuku

The surface can be the object. It will described / sampled by fields. And then you will need to define the STOP of your system. I think this would be a good start.

For the sampling of the STOP, by default the distribution of rays can be uniform, gaussian or cosine cubed. I would recommend checking the apodization type section of the help file for that. 

I hope it helps but do not hesitate if you need more information.
