HOYA 77mm Infrared IR R72 720nm Filter
HOYA R72 720nm INFRARED FILTER.
The Hoya IR Infrared R72 Filter is used for photography in Digital IR and infrared film. Infrared filters will absorb 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 and is often used in crime detection, medical photography, detection of distribution of vegetation, scientific and artistic photography.
