The optical transparency of palladium layers within the wavelength region from 0.5 to 1.1 μm in air and in gaseous mixtures containing hydrogen in the range of 0.1 to 100 vol.% has been studied. The thermal-vacuum deposition method was used to prepare palladium layers on glass substrate. Buger’s law is implemented for layers thickness of order 450 Å. Pd layers of more than 1200 Å are damaged in 100% hydrogen medium. At some hydrogen concentration between 1-10 vol.% a sharp increase in Pd layer transparency is observed that is intrinsic for the first-order phase transition. The layer transparency change speed increases linearly with increasing the hydrogen concentration in gas medium.
