This 77mm IR 720 Infrared Filter with Threaded Filter Ring from Kase can be used for infrared photography with digital cameras and specialized infrared film. This nearly opaque filter blocks all visible light up to 720nm and lets images of how a subject reflects or transmits infrared light to be captured. It is equivalent to a Wratten 89b filter that allows some visible light to pass through for false color rendering, or high contrast rendering in black & white applications.

This filter is made of optical glass with Nano multicoating to reduce flare and optimize light transmission. The coating also provides a protective surface that allows water to bead up for easy cleaning, and also resists scratches and abrasions. The 77mm aluminum filter ring has a slim design suitable for use with wide-angle lenses without vignetting, and features front filter threads for adding another filter, lens hood, or other accessory.
