pygeoml200.materials.surfaces module

Subpackage to provide all implemented optical surfaces and their properties.

class pygeoml200.materials.surfaces.OpticalSurfaceRegistry(reg)

Bases: object

Register and define optical surfaces.

Note on Models

  • UNIFIED model:

    value is the sigma_alpha parameter, the stddev of the newly chosen facet normal direction. For details on this model and its parameters, see UNIFIED model diagram.

  • GLISUR model:

    value as smoothness, in range [0,1] (0=rough, 1=perfectly smooth).

UNIFIED is more comprehensive, but is not directly equivalent to GLISUR. One notable difference is that UNIFIED/ground surfaces w/o specular probabilities set will not perform total internal reflection according to alpha1=alpha2, whereas GFLISUR/ground will do! Polished surfaces should behave similar between UNIFIED and GLISUR.
