Performance Evaluation of an F-Theta Scanning Lens

F-Theta lenses are typically designed to provide high performance in laser scanning systems. With such lenses, the focused spot displacement on the target plane is proportional to the proct of focal length and scan angle. That makes them standard lenses for galvo-scanner-based laser material processing systems. With the help of the scanning source in VirtualLab, we analyze the performance of a given F-Theta lens, by measuring the deviation between actual spot position and desired value and the spot size for different angles.
