We have used the data obtained with the low-dispersion spectropolarimeter HBS as well as those in literature. It is found that the polarization efficiency $p_\\lambda/A_\\lambda$ is proportional to $\\exp(-\\beta/\\lambda)$ in wavelength $\\lambda \\approx 0.4-0.8 \\micron$, where $\\beta$ is a parameter which varies from 0.5 to 1.2 $\\micron$.
