From ca. 750 nm which is directly below the visible red light to approx. 1 mm adjacent to the microwave range. Different materials give off different amounts of emission in different parts of the IR range. Most manufacturers of IR temperature meters have chosen the so-called 3rd atmospheric window which is between 8 \u03bcm and 14 \u03bcm. The advantage is that most materials have a high emission factor, over a wide range of temperatures in this area, which allows the instruments to be used in many different applications.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n<div class=\"wp-block-stackable-divider stk-block-divider stk-block stk-9853e88 avdelare\" data-block-id=\"9853e88\"><style>.stk-9853e88{max-width:800px !important;margin-right:auto !important;margin-left:auto !important}.stk-9853e88 hr.stk-block-divider__hr{width:100% !important}<\/style><hr class=\"stk-block-divider__hr\"\/><\/div>\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-aa971f4\" id=\"jamforbart-med-synligt-ljus\" data-block-id=\"aa971f4\"><style>.stk-aa971f4{max-width:800px !important;margin-right:auto !important;margin-left:auto !important}<\/style><h2 class=\"stk-block-heading__text stk-block-heading--use-theme-margins\">Comparable to visible light.<\/h2><\/div>\n\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-ac667bd\" id=\"principer\" data-block-id=\"ac667bd\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-ac667bd-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-block-column--v2 stk-column stk-block stk-1df04a3\" data-block-id=\"1df04a3\"><style>.stk-1df04a3-container{max-width:800px !important;margin-right:auto !important;margin-left:auto !important}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-1df04a3-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-1df04a3-inner-blocks\">\n<p>Can IR radiation be compared to regular visible light? Yes and no. What is comparable is the general behavior, such as, for example. that the angle of incidence is equal to the angle of reflection. What appears shiny to the eye is often also shiny to the IR radiation and creates reflection. However, it can be misleading to take the comparison too far, e.g. an ordinary window glass that is almost completely transparent to visible light is not at all transparent to IR radiation. In contrast, there are materials that are opaque to the eye but partially transparent to IR radiation.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n<div class=\"wp-block-stackable-divider stk-block-divider stk-block stk-9361748 avdelare\" data-block-id=\"9361748\"><style>.stk-9361748{max-width:800px !important;margin-right:auto !important;margin-left:auto !important}.stk-9361748 hr.stk-block-divider__hr{width:100% !important}<\/style><hr class=\"stk-block-divider__hr\"\/><\/div>\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-5037e96\" id=\"vad-mater-instrumentet\" data-block-id=\"5037e96\"><style>.stk-5037e96{max-width:800px !important;margin-right:auto !important;margin-left:auto !important}<\/style><h2 class=\"stk-block-heading__text stk-block-heading--use-theme-margins\">What does the instrument measure?<\/h2><\/div>\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\" data-block-type=\"core\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\" data-block-type=\"core\">\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-5c01082\" id=\"jamforbart-med-synligt-ljus\" data-block-id=\"5c01082\"><style>.stk-5c01082{align-items:flex-end !important;max-width:800px !important;margin-right:auto !important;margin-left:auto !important;display:flex !important}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-5c01082-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-block-column--v2 stk-column stk-block stk-1c38f5c\" data-block-id=\"1c38f5c\"><style>.stk-1c38f5c{align-items:flex-end !important;display:flex !important}.stk-1c38f5c-container{max-width:900px !important;margin-right:auto !important;margin-left:auto !important}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-1c38f5c-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-1c38f5c-inner-blocks\"><div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\" data-block-type=\"core\"><a href=\"https:\/\/www.nordtec.se\/wp-content\/uploads\/2022\/12\/emission-transmission-reflektion.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"400\" height=\"211\" src=\"https:\/\/www.nordtec.se\/wp-content\/uploads\/2022\/12\/emission-transmission-reflektion.jpg\" alt=\"IR temperature emission transmission reflection\" class=\"wp-image-27482\" srcset=\"https:\/\/www.nordtec.se\/wp-content\/uploads\/2022\/12\/emission-transmission-reflektion.jpg 400w, https:\/\/www.nordtec.se\/wp-content\/uploads\/2022\/12\/emission-transmission-reflektion-300x158.jpg 300w, https:\/\/www.nordtec.se\/wp-content\/uploads\/2022\/12\/emission-transmission-reflektion-64x34.jpg 64w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a><\/figure>\n<\/div><\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-block-column--v2 stk-column stk-block stk-5997026\" data-block-id=\"5997026\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-5997026-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-5997026-inner-blocks\">\n<p>In total, there are three factors affecting the measurement. The most important and usually largest factor is the emission, which is the radiation emitted by the target itself. The most common interference factor is reflection, which is the radiation coming from other sources and reflected to the instrument via the target. The third is transmission, which is radiation passing through the object being measured.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n<div class=\"wp-block-stackable-divider stk-block-divider stk-block stk-dade8a5 avdelare\" data-block-id=\"dade8a5\"><style>.stk-dade8a5{max-width:800px !important;margin-right:auto !important;margin-left:auto !important}.stk-dade8a5 hr.stk-block-divider__hr{width:100% !important}<\/style><hr class=\"stk-block-divider__hr\"\/><\/div>\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-f84e858\" id=\"vad-ar-emissionsfaktor\" data-block-id=\"f84e858\"><style>.stk-f84e858{max-width:800px !important;margin-right:auto !important;margin-bottom:25px !important;margin-left:auto !important}<\/style><h2 class=\"stk-block-heading__text stk-block-heading--use-theme-margins\">What is an emission factor?<\/h2><\/div>\n\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-c5d590f\" data-block-id=\"c5d590f\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-c5d590f-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-block-column--v2 stk-column stk-block stk-0784fc4\" data-block-id=\"0784fc4\"><style>.stk-0784fc4-container{max-width:800px !important;margin-right:auto !important;margin-left:auto !important}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-0784fc4-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-0784fc4-inner-blocks\">\n<p>Since different materials emit and reflect different amounts, a correction is needed to make the IR measurement accurate. This correction is called an emission factor. The starting point is a so-called theoretical blackbody which has zero reflection and transmission and thus has an emission factor of 1, which is written &#8220;e = 1&#8221;.<br\/><br\/>Emission factors for different materials are given in tables and range from e 0.01 to 0.99. Most IR temperature meters have a pre-set emission factor of 0.95 which gives a good accuracy on most measurements below +100 \u00b0C because almost all non-metallic materials such as paper, plaster, wood, rubber, stone, paint, food etc. have an emission factor very close to 0.95.<br\/><\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n<div class=\"wp-block-stackable-columns stk-block-columns
