Absorption Spectra of Single Crystals and Optical Ceramics of Fluorite in the THz and IR Ranges

Transmission spectra of a single crystal and artificial and natural ceramics of fluorite have been obtained in the transparency regions of the material in the THz and mid-IR ranges at room temperature. The reflectance spectra have been measured in the high-absorption region. The optical characterist...

Description
Summary:Transmission spectra of a single crystal and artificial and natural ceramics of fluorite have been obtained in the transparency regions of the material in the THz and mid-IR ranges at room temperature. The reflectance spectra have been measured in the high-absorption region. The optical characteristics of the single crystal and optical ceramics differ only slightly.
