Paper Abstract

Standard measuring condition of d/0 structure has been widely applied on spectrophotometer. Ordinarily, in order to eliminate the impact of light source fluctuation, the inner surface of integrating sphere is selected as reference in the design of integrating sphere system. This design ensures the temporal stability of measurement. But the reflected light of inner surface and diffuse reflection light of sample are both detected as reference signal. It greatly impacts repeatability and error of indication. This paper improves d/0 measuring condition configuration with LEDs light source, and finds the method to reduce the error considering light source and integrating sphere. Then this paper simulates the configuration and establishes experiment for it. The results indicates that this configuration can effectively revise the error which carried by the diffuse light.
