The B+W 55mm Kaesemann High Transmission Circular Polarizer MRC-Nano Filter reduces reflections and glares. It filters out polarized light to provide noticeable reductions in glares and reflections from non-metallic surfaces. It ensures an increase in the saturation of skies and foliage. The filters are fitted with special foils that provide 99.5% light transmission and placed between plano-parallel optical glass. Each glass surface includes multiple layers of anti-reflective coating to prevent internal ghosting. It also includes a multi-resistant coating for better protection. The filter is constructed from Schott glass to ensure better optical clarity and color fidelity.
