633 nm (visible red, cold light)
The Vielight 633 Red releases non-coherent cold light with a wavelength of 633nm in the visible red spectrum, powered by a managed dosage of energy controlled by circuitry. The 633nm wavelength is ideal for blood irradiation, due to its length in the electromagnetic spectrum.
The nasal cavity is rich with blood capillaries, there are more capillaries per cm2 than most organs of the body. Given the rich supply of blood and the thin, permeable membrane within the nasal cavity, this area is well-suited for blood irradiation.
In particular, it is believed that photobiomodulation functions by improving mitochondrial energy production by stimulating the complex IV enzyme, cytochrome c oxidase (CCO), increasing adenosine-5′-triphosphate (ATP) synthesis found within white blood cells.
It is also believed that photobiomodulation helps modulate the oxygenation capacity of red blood cells.
This device can be used in combination with the Vielight 810.
