What is NIR (Near Infra-Red)?
NIR (Near Infrared) light spans approximately 700–1400 nm. NIR penetrates deeper into biological tissue than visible red light; how much reaches muscle or joints depends on wavelength and dose. It is used in photobiomodulation, which is studied for pain relief and recovery. NIR is invisible, so it does not trigger the blink reflex: protect your eyes.
Key Properties
- •Penetration — deeper than visible red; the share of light that reaches muscle or joints depends on wavelength, dose and tissue
- •Targets — cytochrome c oxidase, hemoglobin, water
- •Non-thermal — PBM uses low irradiance; heating is minimal at typical doses
