Urth 43mm Infrared (R72) Lens Filter (Plus+)

The Urth 43mm Infra-Red R72 Lens Filter Plus+ is a professional-grade optical accessory designed for infrared photography applications. This filter effectively blocks all visible light wavelengths below 720nm, allowing photographers to capture the invisible infrared spectrum that exists beyond the human visual range of 400-700nm. Constructed with premium German SCHOTT glass, the filter features an advanced 20-layer nano-coating system that provides superior protection against water, oil, and scratches while ensuring easier cleaning maintenance. The multi-layer coating technology delivers higher maximum light transmission and consistent transmission characteristics, resulting in sharper image quality with finer color reproduction and enhanced depth. The ultra-slim rim design minimizes vignetting risks, and the durable magnalium construction offers long-term reliability. Double-threaded mounting enables convenient filter stacking capabilities and compatibility with standard screw-mount lens caps. This infrared filter is particularly suitable for outdoor and nature photography applications where creative experimentation with infrared light can produce unique landscape imagery. The filter requires compatible camera equipment without built-in IR blocking filters in front of the sensor. With its 43mm thread diameter, this professional optical tool provides photographers with expanded creative possibilities for exploring infrared photography techniques while maintaining optical precision and mechanical durability.
