Emissivity of paper

WebFrom a practical standpoint, emissivity is how reflective or “infrared shiny” a surface is. Reflected background is the infrared energy that is coming from somewhere else, but reflecting off of that infrared shiny surface. Transmissivity is how much of the infrared energy can pass through the material. WebTemperature measurement based on infrared radiation depends on correctly adjusted emissivity. However, emissivity configuration is complex as emissivity is not normally known with precision; it is influenced by radiation …
