I am trying to construct a teflon layer that works as a Lambertian diffuser for optical photons in GEANT. I know how to realise a diffuse reflector, but we want the photons to be partly reflected and partly transmitted.
It is clear how to get Lambertian reflectance, using surface type dielectric_dielectric in the uniform model and setting the finish to ground.
Our problem lies in the transmittance, which we want to be diffuse. In reality, the diffuse property of teflon is due to small cavities in the material. How would one construct a material with this propery in GEANT, or how would one construct a surface that serves as a diffuse transmitter?
Thank you for any suggestions and help!
