Index Vs Temperature Option (dn/dT) Option 2010-TC allows determination of temperature coefficient of refractive index by measuring index for thin films and bulk materials at temperatures as high as 200˚ C. Temperature coefficient data can also be used to calculate thermal expansion coefficients (Kang et al, Appl. Temperature coefficients of refractive index show the changes of refractive indices of the material when the temperature of the material raises by 1 degree C. Usually the coefficient is achieved by averaging the change of the refractive indices of 20 degree C temperature range. Bunting, S.J. International Journal of Thermophysics Phys.
