Vielight: Intranasal - 633 Red (Systemic)

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 cm2than most organs of the body. Five arteries connect to the nasal cavity, while the Little’s area is a frequent site of nasal bleeding. Given the rich supply of blood and the thin, permeable membrane within the nasal cavity, this area is well-suited for blood irradiation.

This device can be used in combination with the Vielight 810

Vielight Intranasal - 655 Prime (Systemic)

This is the laser equivalent of the 633 Red device. This device utilizes a low level (or “cold”) laser diode to release coherent light in the visible red spectrum (655 nm), powered by a calculated dosage of energy to irradiate the capillary-rich nasal cavity. The energy generated by this version is lower than the 633 Red resulting in a more power-efficient design. The Vielight 655 emits low level laser light with a 655 nm wavelength. The light pulses continuously with a power density of 5 mw/cm2.

Vielight Intranasal - 810 Infrared (Brain)
The Vielight 810 is a non-laser intranasal light therapy model. Engineered for gentle brain stimulation, this device complements the systemic effects of the Vielight 633 and 655.
The 810nm near infrared wavelength enables photonic transmission past the intranasal channel to the deep ventral brain areas. Neurons are well-suited for photobiomodulation because they contain mitochondria. 
Before and after QEEG images show the Vielight 810 inducing restorative activity in the brain per 25-minute session. (Link)
