B+W 65-072526 Overview

The B+W 77mm 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 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 B+W 77mm 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
  • 77mm front filter threads allow for use with other filters
  • Plastic case for storage and transport

Used this filter with a Point Grey machine vision camera and a Tamron 8mm 12MP lens for near-infrared photography. Great results.

now I'm going to have fun taking Black & white picture with this filter I think i's going to be like when I was taking B&W with a 25 Red filter when I was using a film camera I hate the big price but when you want quality you have to pay for it I'm going to London & Scotland & Ireland in two weeks & I intend to use it there

Pure IR

Gives a pure IR look on my IR modified Sony A350, but exposure is about 1/30secs with F/8 and ISO 100 in bright sunlight. A device for the IR enthusiast.

Infrared DSLR?

It works OK with my Canon 40D. Exposure time ca. 30 sek at ISO 400 in full daylight. You have to experiment. Focus before You attatch the filter an make correction for the IR wawes (focus at a closer distance than You actually see).

What is 093 means?
Asked by: Khaled
The 093 designation is used to classify this filter as the mid range infrared filter in a series of 3, with the other two being 092 and 099 respectively.

Can I use this with a digital camera, and then convert to monochrome ? Or, do I switch to the monochrome mode and then shoot?
Asked by: Rajiv
Since the human eye taps out at about 720 nanometers, this 900 nanometer filter is not going to let any visible spectrum light into the camera. So regardless of how you set it, when you look at the picture, the image will appear black and white.
