Transmittance and radiation induced absorbance in VUV-UV-visible spectral region were measured in several binary and complex fluoride single crystals at room temperature. Influence of the intentional doping and material stochiometry is demonstrated. X-ray induced coloration and degradation of transmittance characteristics are observed and discussed in terms of creation of various electron (F-like) and hole (VK- and H-like) centers and in terms of near band-edge transitions arising due to imperfect periodicity of the lattice in a general sense. It is shown that VUV characteristics cannot be derived or predicted from those observed in UV-visible spectral region.
