Heliopan 705864 overview

  • 1Description

The Heliopan 58mm RG 830 (87C) Infrared Filter corresponds to a Wratten 87C 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 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 Heliopan 58mm RG 830 (87C) Infrared 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 85% of infrared light waves 830nm or greater into the lens it is mounted onto.

This filter is constructed from Schott glass for increased optical clarity and features a thin brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention.

  • Designed for use with infrared film or digital camera sensors by filtering out near-infrared, visible, and ultraviolet light
  • Allows approximately 85% of infrared light waves beginning at 830nm to pass through
  • Effective for infrared films or other media sensitive to infrared wavelengths 830nm or above
  • Constructed from Schott glass for optical clarity
  • Each glass surface includes four layers of anti-reflection coating to prevent internal ghosting and reflections
  • Filter factor of approximately 200x reduces exposure by about 7.6 stops
  • Thin, brass filter ring helps to prevent vignetting, jamming, and provides additional strength
  • 58mm front filter threads allow for use with other filters
  • Plastic case for storage and transport

    Heliopan 705864 reviews

    58mm RG 830 (87C) Infrared Filter is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from IR only with this baby The door slams shut below 830nm. So far I've gotten good results with Efke IR820 film, but think it may be just too dark for Ilford SFX, which really isn't an IR film. +5 stops and it's still too dark. Haven't tried it on the Mega-zoom digitals yet, but I expect good results with both the Nikon P520 and the Canon SX-50 HS. I give it only four stars solely because of price. The B+W 093 is identical at two-thirds the price.
