Abstract

In this paper, the stray light for an optical splitting system of micro biochemical analyzer is ray tracing by using software FRED and actually measured respectively. The generation and propagation of stray light is simulated and the measures of restraining stray light, such as setting baffle structure, coating critical surface and optimizing light source path are put forward. The results of experiment for improved system show that the stray light coefficient is reduced from 4.6% to 1.2%.
