B+W 65-072474 overview

  • 1Description

The B+W 52mm 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 52mm 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
  • 52mm front filter threads allow for use with other filters
  • Plastic case for storage and transport

    B+W 65-072474 reviews

    52mm Infrared 093 Filter is rated 4.7 out of 5 by 10.
    Rated 4 out of 5 by from Good but challenging IR Filter I got this filter to use for some scientific photography I was doing for a job, but also to have another filter around for general aesthetic IR photography.The filter works great, as is to be expected from B+W, however, as an 87C filter, it makes pure infrared cameras, blocking almost all light below 800nm. Unlike many 680nm or 720nm filters, which allow in much of the near-infrared visible spectrum, this filter only deals with light that is a noticably longer wave-length, which leads to a fairly technical problem when it comes to focusing.Because the wavelength of light is different, focusing behaves somewhat differently. The general effect is that the hyperfocal distance is moved about 15% closer to the camera, with focus adjusted accordingly. You can't focus through the lens either, because the filter blocks all visible light, so there is a bit of trial and error involved in getting a sharp picture if you are just casually using it.Since I need this for work, and need to be precise, I devoted an old Canon 50mm Macro to this filter, taped around the focusing distance window, sat down with a friend who is a math PhD, and calculated out the actual distances and ranges for proper focus with the filter, then marked them on the lens.This works well enough for me, because I primarily intend to use this for studio macro, and if I wanted to do landscape or portraits, I could just bracket and wing it from there.The biggest up side to this is the price. I don't do enough professional IR to justify converting one of my cameras (though I might one day, just for fun). However, many 87c filters for larger lenses can cost more than the camera conversion itself, let alone filters for multiple lenses. This filter was under $, is optically sound, and fits on a 50mm Macro lens, so it does everything I need at significant savings over a full camera conversion.

    Rated 5 out of 5 by from Exactly what one would expect from a B+W IR filter! The B+W 093 (87C) is my current favorite infrared filter. The longer wavelength cutoff (deeper into IR) produces more dramatic infrared images than a filter such as the Hoya R72. I now keep the 093 mounted on my full-spectrum converted Panasonic DMC-G3.

    Rated 5 out of 5 by from exactly what it should be I specialize in scientific and other technical areas of photography. This filter is for a specific purpose and you should know what you're buying before you buy it. This filter is exactly what it is supposed to be. Deep IR isolation, pure grayscale image, no visible whatsoever. Being B + W, of course the glass quality is top notch. No complaints, love it.

    Rated 5 out of 5 by from I'd buy it again This is 'the' IR filter. I should have bought it twenty years ago.

    Rated 5 out of 5 by from Darker is Better Much denser and more pure IR than its sibling 092 and thus affects speed as well. It works well on D200 full spectrum modified camera. Reliable B+W quality and as usual, nice brass ring construction.
