  • Author: Vedant Agrawal, Jay Small
F-theta lenses are essential components in laser scanning systems, enabling high-speed precision applications such as micromachining, additive manufacturing, and medical imaging. They maintain a flat field (image plane) while scanning, ensuring that the focused laser spot moves predictably and linearly with the scan angle. When paired with ultrafast lasers, these systems can achieve significantly smaller heat-affected zones, resulting in reduced material loss and enhanced precision.
