Hoya 55mm R72 Pro Infrared Filter. Infrared light starts in the high-red area of the visible spectrum at around 750nm and goes up beyond 1000nm. This light is not visible to the naked eye. Looking through the R72 filter it looks almost opaque because the filter is only passing light from the very high red edge of the visible spectrum and infrared light.
