Hi everyone,

I am trying to perform a radiation map beneath a thin sheet of polycarbonate.

I have the light transmission, the haze and the rgb values. However, I am wondering if this material should be modeled as a trans or as a dieletric material.

Any suggestion?

Thank you in advance!

Hi Erika,

Well, there are advantages and disadvantages to both. If your polycarbonate is mostly 'specular' transmissive, meaning that the light is not scattered diffusely when passing through the material, dielectric is preferable. Trans will be the best option if the material is very "hazy" or has little visible transmission. The problems with trans are that (1) it does not refract light, and (2) it is not angularly dependent.



Thank you a lot for the explanation!
