The Ice 77mm HB950 Infrared Filter is designed to help capture images of how a subject reflects or transmits infrared light. Infrared light waves occupy the space in the electromagnetic spectrum behind visible light due to their longer wavelengths. Many surfaces and materials react to or emit infrared light waves differently than visible light waves, which provides the potential for photographs of subjects or subject properties that are otherwise invisible to the human eye. Such images require an infrared-sensitive medium such as infrared film or a digital photographic sensor, which may be more effective when used without the infrared-blocking filters frequently built over them.

Conventional light sources such as the sun, photographic strobes, or incandescent lighting may be used to provide infrared illumination. However, because infrared films or digital photographic sensors can be more sensitive to the relatively higher energy and shorter-wavelength visible light those sources also emit, the effects of infrared light can be otherwise obscured. This Ice 77mm HB950 Infrared Filter makes it possible to capture images of how subjects are illuminated by infrared light by blocking ultraviolet, visible, and near-infrared light waves 950nm or less from the lens it is mounted onto. This filter is constructed from optical glass for clarity as well as color fidelity. It features a slim, aluminum alloy filter ring that helps prevent vignetting while remaining durable and lightweight.
