Far infrared wavelengths in nm
WebInfrared saunas often use wavelengths longer than 1,000 nm as part of infrared light therapy — although this is another area where caution is advised due to the possibility of thermal … Far infrared (FIR) is a region in the infrared spectrum of electromagnetic radiation. Far infrared is often defined as any radiation with a wavelength of 15 micrometers (μm) to 1 mm (corresponding to a range of about 20 THz to 300 GHz), which places far infrared radiation within the CIE IR-B and IR-C bands. The long-wave side of the FIR spectrum overlaps with so named terahertz radiation. Different …
