The term “full spectrum light” refers to the entire light spectrum including colors both visible and invisible to the human eye, from ultraviolet (around 300nm) to Infrared (around 1100nm). Between these invisible ranges are the visible spectrums; that which we can see. All color is actually the result of vibration. The entire spectrum of visible light vibrates at frequencies between about 400nm to 800nm (nanometers).
- Violet: 400 – 420 nm
- Indigo: 420 – 440 nm
- Blue: 440 – 490 nm
- Green: 490 – 570 nm
- Yellow: 570 – 585 nm
- Orange: 585 – 620 nm
- Red: 620 – 780 nm
The total light spectrum is much larger than what we see. In fact visible light is only a tiny fraction of the entire spectrum. The light that we can see with our eyes is known as “white light”. It is a combination of all the visible colors of the light spectrum. Do you remember the mnemonic we learned in school, Roy G. Biv? These letters represent the visible colors of the light spectrum or the colors we see in the rainbow, in their proper order. Red, Orange, Yellow, Green, Blue, Indigo and Violet; these are the frequencies visible to us in our light spectrum … notice I emphasized ‘visible’. There are also the ends of the color spectrum, which we cannot see, the extreme left and right of the field. Beyond red is infrared, and on the other end there is ultra violet.
So these different vibrational rates are picked up and detected by our eyes as colors. Higher numbers signify longer wavelengths, which translate into a slower vibrational rate or frequency, the lower the number, the shorter the wave and higher the frequency. The lowest frequency of light we can see appears red, and the highest appears violet, but as we said, the entire spectrum of light is much larger than this (300nm to 1100nm). While we humans cannot see within infrared or the ultra violet areas of the light spectrum with our eyes, animals and insects can. This may account for why animals have been reported in the past to seem to react to spectral entities and ghosts.
Full spectrum light and it’s applications in paranormal research: It is hypothesized that since everything vibrates at various rates that entities, spirits, ghosts etc may be more visible in other areas of the light spectrum than the normal narrow range of light visible to us. Also, since a spirit is believed to be comprised of energy, if that energy vibrated at a rate higher or lower frequency than our own, then we may be able to capture an image of them if we shoot or record with a camera equipped to pick up things that are present in those ends of the spectrum.
Joe Campbell of http://ghosthuntingcamera.com/ actually converts cameras, both still and video, to capture and record images in full spectrum. About which Joe says, “All cameras are sensitive to the invisible spectrums of light and can register this light via their sensitive CMOS (complementary metal oxide semiconductor) or CCD (charge coupled device) sensor. Both types of imagers convert light into an electric charge and process it into electronic signals. Manufacturers install various components that block IR and UV light as these cause undesirable effects in color photography. Generally, a camera is converted to full spectrum by removing these components thus allowing the sensor to process light waves otherwise blocked by the filters. But how does this relate to paranormal research? In simplest terms, if a “ghost” is made of energy and that energy vibrates at either lower of higher frequency levels than our own, then we should be able to “access” them within these energy fields. If those energy fields correlate to the frequency ranges of either ultraviolet or infrared light, then photographing these light waves should allow that energy to be seen and recorded.” Paranormal Research groups around the country, including members from the popular television show “Ghost Hunters”, seek after Joe’s equipment.
Night vision, which has been in use by paranormal investigators for a number of years now, views the infrared spectrum of light, and standard flash photography captures the visible spectrum of light; so it only seems natural that the ultra violet end of the spectrum would be explored and incorporated into the realm of paranormal research. After all, if ghostly apparitions and spectral anomalies can be captured in IR and visible light then they ought to be able to be detected in UV, and if so…what have we been missing?
