Abstract :
The basic principles of flow cytometer are introduced, on the basis of diode pump solid state laser (532 nm) as a excitation source and a high gain avalanche photodiode (APD) arrays as a light detector, a verification opitical system is built. Then, Spherotech Rainbow Calibration Particle RCP-30-5A is used to evaluate the performance of the opitical system, the fluorescence PE signal histogram of RCP-30-5A microshphere shows that the number of individual peaks is close to eight, which is close to the world advanced level.
