Refractive index of powders
Measurement of the refractive index of powder samples with the Becke line microscopic method.
The analysis is suitable for transparent crystalline materials with a particle size larger than 40 μm. Measurements are performed at a 589.3 nm wavelength. Refractive index values from approximately 1.40 to 1.70 are reported with a precision of up to two significant digits. Please note that the method does not directly determine the particle's absorption coefficient (imaginary value).
