- Analysis
- In the UV/vis and infrared up to 8 micron, the real part was determined from the reflectance, while the imaginary part was derived from the transmittance of a 0.05-0.15 mm thick slab (spectra measured with Lambda 19 and Bruker 113v were merged in both cases). In the MIR/FIR, the optical constants were determined by Kramers-Kronig analysis of the reflectance spectrum
