Ultra-high temperature blackbody radiation source

Product Introduction

Definition of black body: an object that can absorb all external radiation energy and radiate all its own energy at the same time.

The main technical indicators of black body: emissivity of black body, diameter of black body cavity, temperature uniformity and uncertainty of radiation temperature. Therefore, in order to ensure the product quality of black body, black body is usually designed according to temperature segmentation. Usually what we call black body is artificial black body. The emissivity of artificial black body is close to 1, but not equal to 1.

The main function of black body is to generate standard radiation at a certain temperature. Therefore, it is mainly used to calibrate various radiation thermometers in temperature measurement, such as optical pyrometers, infrared thermometers, infrared thermal imagers, etc.
