The Urth 72 mm Infrared R72 Lens Filter Plus+ is a professional optical filter designed for creative infrared photography applications. This filter effectively blocks all visible light wavelengths below 720 nm, allowing photographers to capture the otherwise invisible infrared light spectrum for unique and distinctive images. The filter features high-quality infrared glass with an advanced 20-layer nano-coating that provides enhanced protection against water, oil, and scratches while also making cleaning easier. This advanced coating system ensures higher maximum light transmission and a more consistent transmission curve, resulting in sharper images with finer color reproduction and greater depth. The ultra-thin filter frame is precision-crafted from durable magnalium alloy to prevent vignetting while maintaining structural integrity. All filters include double-threaded mounts for filter stacking compatibility or attaching screw-on lens caps. This infrared filter is specifically designed for cameras without built-in IR cut filters and serves as an excellent tool for outdoor and nature photographers looking to explore creative photographic techniques. The product is part of Urth's environmental initiative, which includes tree planting programs and sustainable packaging designs made from recycled materials.
