WebRefractive index and dispersion of acrylic resin (PMMA) Summary The KPR-300 is the refractometer which can measure the refractive index automatically at multiple wavelengths (d-line, C-line, F-line), and calculate Abbe numbers. The multi-wavelength measurement enables you to acquire the relation between refractive index and wavelength (Δn / Δλ). Web15. feb 2016 · The refractive index of ester-based o-phenylphenol urethane acrylates (OPPUAs) was slightly greater than that of ether-based OPPUAs. The difference was due to the electron density increase induced by molecular interactions in the ester polyol, resulting in a higher refractive index.
