Abstract
An anti-reflective thin film coating formed on an optical surface, comprising a multilayer thin-film stack arranged to suppress reflection of incident polarized light within an incident light wavelength range. The multilayer thin-film stack further provides a reflectance edge transition at a wavelength band that lies outside the incident light wavelength range. The reflectance edge transition is arranged to provide phase difference compensation to the polarized light within the incident polarized light wavelength range.
