WebAt-home infrared therapy lamps generally offer wavelengths between 600 and 1400 nanometers (nm). Clinical studies indicate that wavelengths in the range of 630 to 680 nm and 800 to 880 nm are usually the most effective, so it’s important to choose a lamp that’s able to provide those wavelengths. Type WebIf you want a high pass filter, i.e. block wavelengths less than 750nm but allow everything above this wavelength, you'll need to be a bit more cunning. – John Rennie Nov 4, 2012 at 9:11 Add a comment 2 Answers Sorted by: 5 The chart for the reflectance of aluminum tells us that it should do the job for you. data mining used in healthcare https://nechwork.com
