Optical Design and Verification of a New Circular Scanning High-Uniformity Led Collimated Exposure Unit

Project Details


The goal of this project is to develop a scanning LED of parallel exposure machine, using light field distribution calculation technology to construct a scanning LED of parallel exposure machine model. Considering the topic of supporting green energy under Industry 4.0, we use UV-LED to replace the traditional xenon lamps. Set up a pre-compensation system to reach the ability of production line optimization and automatic adjustment. The main purpose of this project is to build a model of a scanning LED of parallel exposure machine and design a LED single-light source modules with a half-angle of 3 degrees and a half-angle of 4 degrees. Then analyze the errors related to the design of the light-source-related mechanisms, and consider the light decay phenomenon of LEDs. Set up a pre-compensation mechanism, analyze the module of the 22 × 25 exposure machine. Finally, trail production of simple cycle scanning exposure machine. It is expected that the scanning LED parallel exposure source device can have a high degree of optical quality.
