The Urth 67 mm Infrared R72 Lens Filter Plus+ is designed for infrared photography applications and operates at wavelengths over 700 nm to capture the infrared spectrum while blocking visible light. Made from German SCHOTT optical glass, this filter features 20 nanocoating layers that provide protection against water, oil, and scratches, ensuring uniform light transmission. The ultra-slim Magnalium edge design minimizes vignetting, and the double-threaded construction allows for stacking filters or attaching screw-on lens caps. With a diameter of 67 mm, this circular filter is compatible with lenses of the matching thread size. The R72 filter series is developed for professional infrared photography, transforming standard landscapes into ethereal scenes with unique tonalities. The nanocoating technology facilitates cleaning and maintains optical clarity over prolonged use. This filter requires cameras without built-in IR cut filters for optimal performance. The Magnalium edge construction ensures durability and long-term reliability. Infrared photography with this filter produces distinctive monochrome or false-color images that reveal details invisible to standard photography. The filter preserves accurate color balance and sharpness across the entire infrared spectrum, making it suitable for artistic and scientific applications. Its compact design and lightweight construction make it practical for field use without significantly burdening camera equipment. Professional photographers appreciate this filter for its consistent performance and optical quality under various lighting conditions.
