The Heliopan 22.5mm RG 1000 Infrared Filteris 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 22.5mm RG 1000 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 70% of infrared light waves 1000nm or greater into the lens it is mounted onto.

Because of the degree to which the Heliopan 22.5mm RG 1000 Infrared Filter blocks the electromagnetic spectrum up to infrared light waves 1000nm or greater, proper exposure is determined by the infrared sensitivity level of the film or imaging sensor behind it. The particular intensity of infrared-emitting light sources, as well as the relative location of the camera and lens on which this filter is used, can also influence exposure.

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.

Q: 4. What additional features are found in the Series 8 filters when compared to those of Series 7?

A: Series 7 or Series 8 simply refers to size only.

Q: 5. Hello! is the holder ring provided with this filter? I need to fit this filter on a 52mm thread lens

A: The Heliopan Series 8 Infrared RG 850 Filter listed above is designed for usage on lenses that have a Series 8 bayonet filter mount. We have no lens mount adapters that would be compatible to connect this filter onto a lens that uses 52mm filter threads. If you own a lens with 52mm filter threads, I would instead recommend the Heliopan 52mm RG 850 Infrared Filter, B&H # HEIR85052, for your usage needs.

Q: 6. Will this fit a PVS-14 objective lens?

A: This will not work with that Model.

Q: 7. Will this work on a Nikon 18-55mm DX VR lens?

A: No, the Hoya 77mm R72 Infrared Filter (B&H# HOIR7277) will not fit directly on a Nikon 18-55mm DX VR lens. Nikon has made many lenses of that description, and they require different sizes of filters. Some of them accept a 52mm filter, while others require a 55mm filter. Please see the number on the front of the lens next to the symbol that looks like a circle with a slash going through it. That is the correct filter size for your lens. If the number on your lens is 52 (i.e. 52mm) then the right size filter is the Hoya 52mm R72 Infrared Filter (B&H# HOIR7252): https://bhpho.to/39ZGP24 However, if that number is 55 (i.e. 55mm) then the filter you'll want is the Hoya 55mm R72 Infrared Filter (B&H# HOIR7255): https://bhpho.to/2Vv5c5qHowever, if that number is 55 (i.e. 55mm) then the filter you'll want is the Hoya 55mm R72 Infrared Filter (B&H# HOIR7255): https://bhpho.to/2Vv5c5q
