Paper Abstract

The light source in spectrophotometer must contain all spectral lines of visible light and have strong enough power in entire visible light spectrum range, so it calls for composition of several light sources. In order to reduce light source error and improve test accuracy, the light source was divided into reference light and test light. The reference light goes into inference path directly to get electrical signals; the test light falls on testing sample after perfect diffuse reflected by integrating sphere, then carries information of testing sample ,and passes through emitting hole, falls on photovoltaic cell to get corresponding electrical signals. Several projects of realizing perfect diffuse reflection of test light from both light source design and structure design are put forward in the essay, and simulated by Tracepro and other optical software. Then analyze and evaluate these several projects to get optimization design.
