Laboratory measurements of unpolarized and polarized absorption spectra of various samples and crystal structures of silicon carbide (SiC) are presented from 1200-35000 cm–1 (λ ~ 8-0.28 μm) and used to improve the accuracy of optical functions (n and k) from the infrared (IR) to the ultraviolet (UV). Comparison with previous λ ~ 6-20 μm thin-film spectra constrains the thickness of the
