High reflectivity polytetrafluoroethylene is formed in the diffuse reflection layer with high reflectivity, and the light is reflected in the integral ball many times. The uniform Lambert surface light source is obtained at the outlet. With high precision and steady voltage DC power supply, it has high stability, high uniformity and multi level radiation calibration source. The standard radiant source of the integral ball is suitable for the radiometric calibration and other optical measurement applications of various optical sensors in different environments (atmospheric environment and vacuum environment).
