Hoya 67mm R-72 Infrared Filter
This filter is used for photography with infrared films. Infrared film is also sensitive to ultraviolet rays and the shorter wavelengths of the visible spectrum so it is necessary to filter out all but the infrared rays. R72 passes only infrared rays above 720nm. It is often used in crime detection, medical photography, detection of distribution of vegetation, etc.
