Abstract: For the laser projection lithography system used for the production of large-area,high processing throughput,and cost-effective printed circuit boards(PCB),its illumination system is simulation-designed and optimized using ZEMAX optical design software,and the optimized results are analyzed.The designed results,including uniform of image plane,size and shape of beam geometry,aberration as well as matching of illumination system with projection lens,fulfill the demands of laser illumination syste...
