The B+W 49mm Infrared 093 Filter corresponds to a Wratten 87C filter and 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 provide 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 B+W 49mm Infrared 093 Filter makes it possible to capture images of how subjects are illuminated by infrared light by blocking near-infrared, visible, and ultraviolet light waves while allowing approximately 88% of infrared light waves 900nm or greater into the lens it is mounted onto.

This filter is constructed from Schott glass for increased optical clarity and features an F-Pro brass filter ring for durability as well as jamming prevention.

  • Designed for use with infrared film or digital camera sensors by filtering out near-infrared, visible, and ultraviolet light
  • Allows approximately 88% of infrared light waves beginning at 900nm to pass through
  • Effective for infrared films or other media sensitive to infrared wavelengths 900nm or above
  • Constructed from Schott glass for optical clarity
  • Non-coated
  • Filter factor of approximately 20 to 40x reduces exposure by about 4.3 to 5.3 stops
  • F-Pro brass filter ring helps to prevent jamming and provides additional strength
  • 49mm front filter threads allow for use with other filters
  • Plastic case for storage and transport
