Glas-Pro software, developed by HANGLAS Research and Development Center, allows simulation for spectral characteristics simply by adding transition elements, without an experiment to directly add transition elements.

• Entire glass manufacturing process which needs prediction of changes in spectral characteristics following addition of transition elements.
• Entire glass manufacturing process which needs prediction of changes in spectral characteristics due to the changes of Redox.

• Spectrum, spectral characteristics and color can be calculated from absorption coefficient for each element according to the concentration by adding or reducing transition elements such as FeO, Fe₂O₃, CoO, Cr₂O₃, CuO and NiO (CIE L*a*b*, TL, TE, TUV, Dominant Wavelength and Purity)
