Information

F-theta lenses are commonly used in high-performance laser scanning systems to generate focal points whose lateral displacements linearly depend on the scanning Angle. This is the characteristic required in common applications such as laser material processing. In VirtualLab Fusion, we provide scanning light sources for such cases and use different field solvers to easily evaluate the performance of such scanning lens systems.

Using the scan sources in VirtualLab Fusion, we can analyze the performance of the F-Theta lens by measuring the focal position and spot size deviations from different scan angles.

The scan source in VirtualLab Fusion defines a multi-mode source that radiates to several predefined directions, which is useful for modeling and evaluating laser scanning systems.
