4Sight™ data analysis software provides state of the art 3D display capability for data from laser interferometers and other metrology systems. In fact, all of the wavefront graphics on our website were produced using 4Sight. 4Sight makes it incredibly easy to view wavefront data in a variety of ways. The two basic displays are contour plots and 3D perspective plots that can be rotated in real time. It is easy to view the data in different color palettes. You can even create and edit your own color palettes.
