The human eye can see electromagnetic radiation with a wavelength of 400-700nm. This is called the visible light range. Anything above this is called infrared light.
The infrared filter filters out almost all wavelengths of visible light, only allowing light with a wavelength longer than 720nm to pass through, allowing you to capture light invisible to the human eye.
The Urth Plus+ filter series uses German B270 SCHOTT glass with a 20-layer nano coating, which makes the filter easier to clean and provides better protection against water, oil and scratches.
