Optical detection system of biochemical analyzer in laboratory based on Spectrophotometry

In order to further improve the accuracy,intelligence and multi parameter of biochemical analysis instruments in the laboratory,an optical detection system based on spectrophotometry is proposed.The multi input and one output coupling optical fiber is used to separate various incident monochromatic light with different wavelengths in a certain spectral range,and detect each parameter index in turn;the measurement error of the system is controlled in the form of fixed components,The accuracy and consistency of measurement results are ensured.The experimental results show that the proposed optical detection system can meet the requirements of multi optical parameter measurement,and can play an important role in the development of miniaturization and automation of biochemical analyzer.
