Useful for minimizing reflections and glare and enhancing the overall color and tonal saturation is the 37mm Ariel Circular Polarizing Filter from Vu Filters. Utilizing HiVu Polarization Optics it filters out light that has become polarized due to reflection from a non-metallic surface, resulting in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

Further enhancing image quality is a White Balanced Multi-Coating that ensures that there is little to no color shift. Also, a Flat Wave Coating makes the filter's front surface exceptionally smooth for easier cleaning and maintenance. There is also a UV Rejection Coating that reduces UV reflections and ghosting.

This filter is hand crafted and individually inspected for ensuring quality and uses impact resistant Ultra-White Schott glass for maximum performance. The glass edge is black to prevent internal reflections and helps seals the edge. Also, the black anodized CNC aluminum filter frame has Integrated Optik Lock technology that seals the front of the lens from the environment for additional protection.
