The Urth 37mm Infrared R72 Lens Filter Plus+ is a professional photography accessory designed to capture infrared light beyond the visible spectrum. This filter blocks all wavelengths below 720 nm, allowing only infrared light to reach the camera sensor, which creates unique photographic effects where foliage appears white and the sky takes on dramatic dark tones. Constructed with high-quality German SCHOTT glass, the filter features 20 nanocoating layers that provide enhanced protection against water, oil, and scratches while ensuring easier cleaning. The advanced coating technology allows for higher maximum light transmission and consistent transmission properties for superior image sharpness and color fidelity. The ultra-thin edge design prevents vignetting with wide-angle lenses, while the robust magnalium construction ensures long-term reliability. The double-threaded mount allows for filter stacking compatibility and accommodates standard screw-thread lens caps. This infrared filter requires compatible camera equipment, as it does not function properly with cameras that have built-in IR cut filters. Ideal for landscape and nature photographers seeking creative experiments, the 37 mm filter thread size fits corresponding lens diameters. The professional construction ensures optical clarity and consistent performance for infrared photography applications, where capturing invisible light wavelengths transforms ordinary scenes into extraordinary visual compositions.
