Hi!
I have some questions regarding the optical surface. The AI's explanation for this section of the user manual is as follows: For the UNIFIED model, the surface definition rule in dielectric_dielectric is "coating surface treatment method + coating position relationship". For example, "polishedfrontpainted" means that I am using a reflective layer similar to ESR, and there is a gap between the reflective layer and the crystal. The surface of the crystal is controlled by SigmaAlpha, a value of 0 indicates that the crystal is in a completely polished state, and a value greater than 0 indicates a rough state. I would like to know if this statement is correct?
If it is correct, does it mean that regardless of the surface treatment method I set for my coating, as long as I do not set SigmaAlpha, then the crystal surface treatment method will always be the default and will not change (assuming the default is 0, then the crystal surface will always be in a completely polished state)?
