I hope after years of research in IR I don’t find out I’ve been using FIR instead of NIR without noticing.
Obviously you can have a device emitting in a specific wavelength with different levels of emitting power.Yes, most pads include emission in red light too - it makes much easier to check when they’re switched on and working; red light emission also has a positive effect on dermis cells, so it’s not useless. That’s why the chips I mentioned above, each with 2 emitters in 850nm and 1 emitter in 660nm, kind of became mainstream.
I am always happy to learn! I am by no means a scientist nor engineer. Full cut specs:
Red Light (660NM): Activates cell regeneration, reduces inflammation and pain, increases collagen production
- Infrared Light (850NM): Penetrates deep, reaching tissue and joints to activate the auto-repair of cells
The strength of the lights is:
141 mW / cm, 1 inch away from the skin
200 mW / cm when in contact with the skin
Again, flaunting my cursory math skills as well, would the 200 mW/cm closely approximate the 2115 mW/m on your readings? One inch away then dissipates. I got the NIR wave length range I quoted from various web sites where I just plugged-in near infra red and far infra red wave lengths and got that upper end of 1400 for NIR. I did see some references to a mid-range. As for longevity, I have not tracked, and I also used extensively for knee pains from running last year. I have not dedicated efforts to gain with it so I can’t tell you results in that regard, I just know it provides a distinctly different feeling of heat for me to use around a tube. My focus is more on general maintenance and function at the moment.
