Scattering Modelling: Different ABg sums for different angles


Hello,

I have a question to this article:

How to use multiple ABg profiles to define an object's surface scatter property – Knowledgebase (zemax.com)

 

I have just implemented my scattering ABg-File model in Zemax OpticStudio with 3 profiles based on measurements.
This scattering model fits well for AOI=10°, however, for AOI=50° and AOI=80° it does not fit to my measurement data. Thus I would like to use separate ABg sums for these 3 Angles.

Is this possible in Zemax?

Do I need to program a DLL?

 

At least for single ABg models per Angle I can use the Scatter Catalog, but not for ABg Sums, right?

Fitting ABg scattering coefficients from raw measured data – Knowledgebase (zemax.com)

Best Regards,
