Here is a good article!

1. Near Infrared: A Tutorial
Introduction
Near infrared light consists of light just beyond visible red light (wavelengths greater than 780nm).

2. NEAR INFRARED:
Between about 0.8 to 1.1 microns we can use the same observing methods as are use for visible light observations, except for observation by eye. The infrared light that we observe in this region (near-IR) is not thermal (not due to heat radiation). Many do not even consider this range as part of infrared astronomy. Beyond about 1.1 microns, infrared emission is primarily heat or thermal radiation.

Near-Infrared:

SPECTRAL REGION WAVELENGTH RANGE: Near-Infrared (Near-IR)
(microns)
(0.8-1) to 5
(Nanometers)
(800 nm - 1,000 nm) to 5,000 nm

[Note: Other "experts" place the lower range of Near-IR at 0.78 microns (780 nm) and the upper range of Near-IR at 3,000 nm (3.0 microns) to 3,700 nm (3.7 microns). However, there is a "growing consensus" that the Near-IR "range" should be from 900 nm - 1600 nm for some sound "biological effect" reasons with 900 nm - 1200 nm being the wavelengths of primary "biological" importance. Did you know that facultative pigmentation, i.e., a "tan" only provides protection out to 1200 nm?]

TEMPERATURE RANGE: Near-Infrared
(degrees Kelvin)
740 to (3,000-5,200)

The "bottom line" is that there is a big difference in the biological effect of Near-IR (however you define it) and 633 nm.

Now is that 633nm ONLY EFFECTIVE at EXACTLY 633nm or is there an "effective range". If I bought a laser pointer that operates at 645nm is this the same thing?

No it is not the same.

Anything outside of 630 to 636 can inhibit the production of collagen. This is where Lumiere excels over ALL current LED phototherapy units. PTL has a ton of intellectual property and patents protecting their cooling mechanism that allows the LEDs (which produce massive heat for their size) to stay at the coveted 633 +/- 3nm
PTL also makes the Omnilux device used by Doctors around the world (same device, however, you "the Lumiere operator" can not make medical claims) Sound familiar?!

Thanks Don, 633 IS NOT IR

John, you can even see this in the chart you posted.

JOHN @ URI

Red is a color at the lowest frequencies of light discernible by the human eye. Red light has a wavelength range of roughly 630-760 nm.

Sorry, I was close!

Tom:

You said "Anything outside of 630 to 636 can inhibit the production of collagen." and I think the literature shows that the "beneficial range" is a little wider than that. Probably more like plus/minus 10 nm (i.e., 623 nm - 643 nm) and some "experts" feel that the range is even broader, i.e., 590 nm - 690 nm.

Don,

I am making reference to Dr. Colin Whitehurst (he developed the original RED light treatment i.e., the Paterson Lamp for the Paterson Cancer Institute). His findings as the pioneer and leader in this technological field show maximum efficacy at the fore mentioned 633 with positive effects within +/-3nm. He firmly believes that anything outside of this parameter will compromise the permeability of the cellular membrane, thus effecting the ability of any device such as laser, LED or otherwise.

Not questioning you Don (you are one sharp dude). I have seen other reports showing what you are stating, however I have also seen the clinical findings and believe that Dr. Whitehurst is correct.

The Lumiere process is much more than "the light" however. Lumiere uses this light to deliverer topical ingredients known to reduce the signs of ageing in order to improve upon the already impressive results of the 633nm wavelength, much like the Dr.'s at the Paterson Cancer Institute use the light to deliver topical ingredients used to kill cancer.

Permeability of the cellular membrane is the key to this technology.

Thanks,
Tom

How are your four new lumiere salons doing?

I think you already know what I am upto, especially after quoteing your statement about sunless.

Since I am opening 4 new Lumiere salons this year, I must be a strong beliver.

Come to Indiana my chlid, come and see the light.

How are your 4 new salons doing?

TanWorldOrder

so is the laser pointer the same thing?

Did House of Tan open 4 new Lumiere Salons ? (since the June 2005 post?)
