3 Overview

500K ~ 1000K blackbody radiation (referred to in bold) refers to the working temperature range of 500K ~ 1000K (Fixed or adjustable temperature working temperature point some work) inside its degree of radiation emitted M available Stefan - Boltzmann constant Law M = εσT4 described radiation source. Blackbody infrared components commonly used in the infrared instruments and machine performance testing, By field of application is divided into two kinds of standard blackbody blackbody work. Blackbody radiation cavity structure shown in Figure 1. Including blackbody chamber, heating coil, insulation, temperature control Measurement and control system and the chamber temperature thermometer. Chart 1 standard blackbody radiation sources
