Optical constants of Na and Li in the form of evaporated thick solid films have been determined between 0.6 and 3.8 eV by ellipsometry. Measurements were made at room temperature through the quartz substrate at the quartz-metal interface. The optical conductivity of Na agrees well with the earlier data of Smith, while that of Li exhibits considerable differences from the results of Mathewson and Myers. The parameters of the nearly-free-electron model have been derived from the real part of the dielectric function, and the results compared with previous data.
