Abstract：Objective To design a reference light source for measuring chemiluminescence immunoanalyzer. Methods
According to the principle and technical characteristics of chemiluminescence immunoanalyzer, the reference light source was
considered and designed from three aspects of content, index and scheme to evaluate the repeatability, stability and linearity of the
instrument. Results The average value of repeatability test was 9957.50, the standard deviation was 42.73, and the coefficient of
variation was 0.43%; the maximum value of stability test was 9937, the minimum value was 9802, the average value was 9859.6, and
the relative range was 1.37%; the linear correlation coefficient r=1.00000. Conclusion This design can realize the stable light output
of PIVA level or even lower light intensity level. By replacing the interference filter, the spectral output of any central wavelength can
be realized, so as to simulate different chemiluminescence reagents. The linear light output can be realized by replacing the second
neutral filter, which has the advantages of simple structure, good applicability, low cost and accurate measurement results.
