Fast calculation of laser divergence angle based on Isight

After a Galileos beam expander is designed, hundreds or thousands data of divergence angles corresponding to the displacements of lens group are calculated to ensure light spot size. Based on the Design of Experiment (DOE) module in Isight, fast calculation is implemented using codeVs command syntax. Hundreds data are obtained in 2 hours. Efficiency is greatly improved, and manual error is avoided thanks to software operation.
