• Used for infrared photography applications with digital cameras and specialized IR film
• Blocks all visible light up to 720nm for photographing subjects and details that are not normally visible.
• Variable filter factor depending on ISO sensitivity and lighting conditions.
• Can be paired with colored black and white contrast filters to change the colored or contrast effects with this filter.
• Made in Japan

Used for photography with infrared films. lnfrared 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. Often used in crime detection, medical photography, detection of distribution of vegetation, etc.

In ordinary photography with infrared film or infrared color film, the Y(K2), O(G), R(25A) and other filters can also be used to change the contrast or color effect.
