The Heliopan 24mm RG 780 Infrared Filtercorresponds to a Wratten 87 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 24mm RG 780 (87) 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 88% of infrared light waves 780nm 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.

Q: 1. Is it possible to see through plastic with this filter on a Nikon Z7ii? Or does it require other special equipment?

A: The Ice 77mm HB760 Infrared Filter has a filter factor of ~1000x and ~10 stops of ND. You will not be able to see through the glass unless you are aiming the filter directly at a bright light.

Q: 2. How well will this work with a near-IR film like Ilford SFX?

A: The Ice 52mm HB760 Infrared Filter blocks UV / Visible Light under 760nm. This will not work with Ilford SFX 200 Black and White Negative Film that only has sensitivity up to 740nm. Near IR film does not have the sensitivity to work with this filter.

Q: 3. will this work on sony alpha cameras? i heard you need to modify the camera in order for this to work? I have a7s and a6500

A: The filter works perfectly without any changes to the camera, do you need to do some post processing and you can check on YouTube. I highly recommend the filter

Q: 4. will it work with a Pentax 645D?

A: mmmmI' don't think soThat camera is too new.The IR filters works better with older digital cameras like the Nikon D50, D70 and D80, D100 (2001 - 2006)

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. Hello, can I use this filter with my Canon EOS Rebel T5i?

A: there are some youtube videos on testing your sensory if it is responsive to IR by using a home device remote controller; a difficult lens to use as is very dense to light and hard to focus well; so far, my results are disappointing; good luck

Q: 7. Will this filter work well on a Nikon D850?

A: My base settings on the D810 was, 30 sec, f/8, ISO 400. Early morning with shade. I was pleased with the results.

Q: 8. Will this work with a Canon R5?

A: The Hoya 67mm R72 Infrared Filter will fit any lens that has a 67mm filter thread. You can use the filter on a lens that is attached to the Canon R5.

Q: 9. All of my filters are for 1.25 mm . My camera is a Canon T3 Rebel . Will this filter fit in my lenses (1.25 mm) or on my camera?

A: The Heliopan 30mm RG 1000 Infrared Filter will fit a lens with a 30mm diameter front

Q: 10. What is the response curve of this filter?

A: Unfortunately, the Ice 77mm HB950 Infrared Filter does not have a published response curve according to the manufacturer.
