Haida 100 Series Infrared (IR) 720 Optical Glass Filter - HD2506A

Designed to block all visible light, this 100 x 100mm Infrared 720 Filter from Haida is well-suited for those looking to get into infrared photography. It is made of optical glass and has a dark appearance due to its opaque quality. Featuring a thickness of 2mm, it can be used with the Haida 100 series filter holder or other compatible holders.

The filter works by blocking electromagnetic radiation with a wavelength shorter than 720nm, which includes the entire spectrum of visible light as well as ultraviolet light. This results in an image that is made entirely with infrared radiation, leading to interesting otherworldly effects such as dark skies and bright white foliage. Suitable mediums for this kind of photography include digital sensors, especially those that have had their infrared-blocking filters removed, and infrared film designed for this specific purpose.
