We report an optical study of transition metal dichalcogenide 2$H$-TaS$_2$and Na intercalated superconductor Na$_x$TaS$_2$ over a broad frequency rangeat various temperatures. A clear gap feature was observed for 2$H$-TaS$_2$ whenit undergoes a CDW transition. The existence of a Drude component in$\sigma$$_1$($\omega$) below T$_{CDW}$ indicates that the Fermi surface of2$H$-TaS$_2$ is only partially gapped in CDW state. The spectral evolution oftwo different Na$_x$TaS$_2$ crystals further confirms that the partial gapstructure observed in 2$H$-TaS$_2$ has a CDW origin. The CDW mechanism for2$H$-TaS$_2$, the competition between CDW and superconductivity inNa$_x$TaS$_2$ system are discussed.Comment: 4 figures, 4 page
