Depending on the make and model, an infrared thermometer is actually reading the temperature above, below or around where you see the laser. Some infrared thermometers, like the IR Pro Series and the IR-IND are equipped with two lasers.
Infrared generally refers to the portion of the EM spectrum that begins just beyond the red portion of the visible. region, and extends to the microwave region at longer wavelengths. Most astronomers measure the wavelength of. IR radiation in microns (Âµm), or millionths of a meter. A human hair, for example, is about 70 Âµm. wide. The visible spectrum extends from about 0.4 Âµm (violet) to 0.7 Âµm (red), and the infrared spans the broad. region up to hundreds of microns.
