- Analysis
- In the vis and infrared up to 8 micron, the imaginary part was derived from the transmittance of a 0.047 mm thick slab while the real part from 1 to 8 micron was determined from reflectance (spectra measured with Lambda 19 and Bruker 113v were merged). In the MIR/FIR, the optical constants were determined by Kramers-Kronig analysis of the reflectance spectrum. The real part was extended to the UV/vis (0.25 - 0.9 micron) by merging with data measured by spectroscopic ellipsometry (SOPRA ES4G, by A. Zuber, Fraunhofer IOF Jena).
