Breakthrough Photography X2-IR-49MM overview

  • 1Description

The Breakthrough Photography 49mm X2 720nm IR 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 that are 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. The Breakthrough Photography 49mm X2 720nm IR Filter makes it possible to capture images of how subjects are illuminated by infrared light by blocking ultraviolet, visible, and near-infrared light waves below 720nm from the lens it is mounted onto.

To prevent internal ghosting and reflections, each glass surface includes four layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with X2 720nm IR filters provides an additional fifth layer over the front MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

This Breakthrough Photography X2 720nm IR filter is constructed from optical glass for clarity as well as color fidelity and features a thin filter ring to minimize the potential for vignetting. It is also weather sealed, helping to prevent dust and moisture from reaching your front lens element.

Designed for use with infrared film or digital camera sensors by filtering out near-infrared, visible, and ultraviolet light.
Allows infrared light waves at 720nm or above to pass through.
Effective for infrared films or other media sensitive to infrared wavelengths 720nm or above.
Constructed from optical glass for clarity and color fidelity.
Multi-coated to prevent internal ghosting and reflections.
Nano-coating provides an improved beading effect with water for more efficient cleaning.
Weather-sealed design prevents dust and moisture from reaching front lens elements.
3.5mm, thin filter ring helps to prevent vignetting.
49mm front filter threads allow for use with other filters.
Side knurlings to provide a more textured grip when mounting or removing it from a lens.
5.9 x 5.9" microfiber cleaning cloth included for filter maintenance.
