Influence of UV irradiation on optical properties of the nitrogen doped
 diamond-like carbon (DLC) films was studied. Transparency spectra of the initial, UV
 irradiated and concentrated UV irradiated films were measured. Dependences of the
 optical bandgap on the nitrogen content were obtained from these spectra. Raman
 measurements revealed a decrease in the graphitic cluster size by two times after UV
 irradiation. It was shown that concentrated UV irradiation leads to smaller changes in
 comparison with nonconcentrated UV. Physical mechanism of air oxygen embedding
 into the DLC structure under UV irradiation is proposed to explain the changes in the
 properties of the films.
