Abstract
In order to study effect of optical route of two-photon polymerization on polymerization result, firstly, the mainly three parts i.e., beam expander, scanning galvanometer and focus lens were designed with ZEMAX software. Secondly, the whole optical route was simulated after combining the three parts together. The changes of the beam were monitored at different positions of the route with a detector. The variation of laser energy distribution could be seen in simulated diagrams and the influence of beam expander on the final focal results was analyzed. The results show that the larger the amplification multiple of the beam expander the smaller the distance between the beam expander and the light source, and the higher the energy density on the focus spot. The simulation results also provide the basis for actual experiment system construction.
