NiSi 138mm Mounted Linear Polarizing Filter

The NiSi 138mm Mounted Linear Polarizing Filter is designed for professional cinema and video applications. Built with water white optical glass and an aluminum mounting ring, this rotatable filter fits directly into the 138mm donut slot of professional matte boxes. It reduces reflections and glare from non-metallic surfaces such as water and glass, whilst simultaneously enhancing colour saturation and reducing haze in landscapes. The filter also reduces distortion and controls light transmission from screens, making it an essential tool for cinematography and professional video work.
