Webinfrared radiation, that portion of the electromagnetic spectrum that extends from the long wavelength, or red, end of the visible-light range to the microwave range. Invisible to the eye, it can be detected as a sensation of warmth on the skin. The infrared range is usually divided into three regions: near infrared (nearest the visible spectrum), with wavelengths … WebIs IR long wavelength? Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible …
WebAlpha-One Electronics supplies long IR wavelength LEDs. We supply an extensive range of spectral wavelength including λp1060nm, λp1300nm, λp1450nm, and λp1650nm of infrared light. The principal natural greenhouse gases in order of their importance are water vapor H 2O, carbon dioxide CO 2, ozone O 3, methane CH 4 and nitrous oxide N 2O. The concentration of the least common of these, N 2O, is about 400 ppbV. Other gases which contribute to the greenhouse effect are present at pptV levels. These include the chlorofluorocarbons (CFCs) and hydrofluororcarbons (HFC and HCFCs). As discussed below, a major reason that they are so ef…
