Wavefront Error is a measure of amount of distortion the lens introduces to the wavefront.
Wavefront error analysis can be used to measure and analyze the distortion in the wavefront caused by the lens. This analysis provides valuable information about the quality of the lens and can help to identify any imperfections or aberrations in the lens design. By analyzing the wavefront error, engineers can optimize the lens design to reduce the distortion and improve the quality of the laser beam.
Use common analysis tools to simulate actual lens performance
The point spread function (PSF) and Extended Source plots are valuable tools in laser lens design because they provide information about how the lens focuses light and how the focused spot is affected by aberrations in the lens. They provide the spatial distribution of the laser beam at focus resulting from the laser source passing through a laser lens.
How a beam performs through the focal plane is also important.
Thru focus spot diagrams are a useful tool for analyzing the performance of laser lenses and identifying ways to improve their performance. Thru focus spot diagrams show how the laser beam is focused by the lens at different distances from the lens. By analyzing these diagrams, engineers can gain insights into the performance of the lens and make adjustments to optimize its performance.
