The design was optimized for maximum signal intensity by simulation and experiments. The size of focal spot in the micro-channel capillary was optimized. Fluorescence signal was enhanced 2～3 times when increasing the diameter of focal spot from 10μm to 50μm (full of the inner wall of capillary), through which the sensitivity and signal-noise ratio were also improved. A technique of using refractive matching liquid was presented. The fluorescence signals were boosted up and the signal collection efficiency was also meliorated when using this method.

Finally the energy distribution of the spot was reconverted and obtained through computer processing of the measurement data.
