Urth Infrared (R72) Lens Filter (Plus+) The Infrared (R72) Lens Filter Plus+ from Urth cuts all visible wavelengths of light so you can capture invisible infrared light for uniquely stunning images. The Infrared Filter Plus+ cuts all wavelengths below 720nm allowing you to capture the otherwise invisible light in the infrared range. This filter is an exciting tool for creative experimentation for outdoor and nature photographers. The Plus+ range features 20-layers of nano-coating providing easier cleaning and better protection against water, oil and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for sharper images, finer colours and greater depth. This filter is not compatible with cameras that have an IR blocking filter in front of the sensor. The filter is double-threaded for stacking filters or using screw-mount lens caps. Capture stunning landscape, nature and outdoor photographs with the infrared filter. Explore the unique details revealed by infrared light. The filter lets you capture the dramatic high-contrast details of usually invisible infrared light. The Infrared (R72) Filter Plus+ cuts all wavelengths of visible light so only infrared light (above 720nm) reaches your camera sensor. It is coated with a 20-layer nano-coating for professional clarity, true colour balance, and exceptional infrared photography. The consciously designed ultra-slim rim avoids vignetting and our durable magnalium is guaranteed for life.
