What are Full Spectrum Cameras and Camcorders used for? How do they Work?

full spectrum vs visible light

Many people online often misunderstand the term Full Spectrum, usually suggesting that it refers to the Electromagnetic Spectrum.  We often find people adopt this tactic to put you off from buying from experienced companies like ourselves that correctly understand how their products work and how to brand them accordingly.  We are happy to answer any questions, so feel free to ask……

So what is a Full Spectrum?  Let us explain……

The Electro Magnetic Spectrum covers a broad range of wavelengths from Radiowaves, Microwaves, Visible Light, Ultra Violet and Infrared Light, X-Rays, Gamma Rays.

Our eyes visualise a small part of the Electro Magnetic spectrum, the part we call visible light, or more commonly ‘colours’. The eye an only detect three different wavelengths of light, corresponding to green, blue, and red. Combining these three signals in the brain creates millions of different shades.

A camcorder works is a very similar way to replicate our vision, with an opening through which the light enters, a lens for focusing and a light-sensitive membrane at the back.

Our eyes are also protected from UV and IR light by our Cornea, to mimic this the camcorder uses a ‘hot mirror’ to absorb or reflect these wavelengths.

During the conversion process, Infraready remove the hot mirror and replace it with a component that will pass UV, Visible and IR light…….this is otherwise called the ‘FULL SPECTRUM’ of light, hence the devices name ‘FULL SPECTRUM CAMCORDER’.

 

What are they commonly used for?

for Paranormal Research, UFO sky watching, Private Investigation / Night Vision Surveillance and for the filming of Nocturnal Wildlife such as Bats, Beavers and Badgers.

If paired with IR illumination our devices will allow the user to capture footage in complete darkness.  Amazingly this can also view this in real time on the LCD screen.

 

Can Infrareadys Full Spectrum devices be used for everyday use and to isolate certain parts of the light spectrum? Yes… Please read on….. 

Some of our devices employ a filter thread on the lens housing that can accommodate screw on filters.    A wide variety of filters are available to isolate certain wavelengths, correct the camera colours for everyday use, or for other effects can be found in our store.  The most popular filters our customers purchase are..

1) The Colour Correction Filter – This absorbs or reflects UV and IR, only  letting Red, Green and Blue light to pass to the sensor.  This allows the device to be used for everyday movies or the family, kids, pets etc.

2) Infrared 1KIR – This filter blocks coloured light and part IR, only allowing wavelengths of above 1000nm to pass to the devices sensor.  This type of filter is popular with Sky watchers in the daytime as it is often used to track UFOs that are cloaked by IR.  The filter can also achieve the Faux Xray effect, allowing it to see through certain materials, an effect that Sony Nightshot removed from their devices several years ago.

Using filters with the device is simple, screw in place, then set the white balance in the devices menu to custom.

 

How does the device record in the dark?

As suggested earlier, the modification we perform allows Infrared light to pass to the devices sensor.  Although our eyes can’t see Infrared, the modified device will yeild this type of light and process it to allow the user to record and view it as they would normal visible light.  If the device is paired with IR light and set up correctly using the white balance settings, the appearance of the resulting footage will be near monochrome in appearance.  Pink or Purple hues will be achieved if incorrectly set, but some users prefer this effect.
