Field Curvature Analyzer
Abstract
In VirtualLab Fusion, the field curvature of a lens component can be analyzed precisely, with the field curvature analyzer. The field curvature curve can be calculated with respect to angle or object height, and shows the aberration in both sagittal plane and tangential plane.
This tutorial shows how to set up the parameters in the field curvature analyzer.

How to Format VirtualLab Fusion Results
This tutorial demonstrate how to customize and format a detector result according to personal favor or specific requirements of a report or publication.
Use Case
Focus Investigation behind Aspherical Lens
A laser diode with asymmetric divergence and astigmatism is first collimated and then focused. Evolution of the field in the focal region is investigated in detail.
Use Case
Performance Evaluation of an F-Theta Scanning Lens
With the scanning source in VirtualLab Fusion, we analyze the performance of an F-Theta lens, by measuring the focal spot position deviation and the spot size for different scan angles.
