Schneider 138mm Unmounted Circular True-Pol Filter

While the 138mm Unmounted Circular True-Pol Filter may seem like a simple accessory, it's an essential tool for photographers looking to capture stunning, glare-free images. This high-quality filter is meticulously crafted by laminating a polarizing film and a 1/4-wave retarder plate between two sheets of pristine, water-white optical glass. This construction process ensures the filter's durability and resistance to edge chipping and delamination.

An additional edge seal process is implemented to further minimize edge reflections and flare, enhancing the overall image quality. The filter's primary function is to suppress reflections and glare by selectively filtering out light that has become polarized due to reflection from non-metallic surfaces. This results in a significant increase in the saturation of skies and foliage, as well as clearer, more vibrant imagery in hazy conditions.

One of the key features of this filter is its high extinction ratio, a unique selling point that sets it apart from other filters in the market. In terms of application, the 138mm Unmounted Circular True-Pol Filter outperforms traditional Linear True-Pol filters. It's specifically designed to prevent viewfinder blackout when used with cameras that have polarizing elements in the beam-splitter of their viewing system.

Furthermore, this Circular True-Pol filter is an ideal choice for digital cameras and autofocus lenses. Unlike linear polarizers, it won't disrupt auto exposure and focus features, making it a versatile and valuable addition to any photographer's toolkit.
