Hello,

 

I have a measured BRDF file with 5 AOI in 3 orientation of the material, I would like to know if you also support converting its format to the suitable format of the OpticStudio? because transformation of the angles are complicated and very time taking for me. origin of the coordinates and definition of the azimuth and longitudinal angles are different in comparison to zemax!

Hi!

No currently we don’t have any tools to convert from a given format to OpticStudio format. Maybe some users will have a tool to share?

I guess you probably know this but we have two articles that describe the OpticStudio BSDF format.
