AFM | Celgard(R), 1um, 23Hz, Perpendicular Mesh Orientation | Bruker Dimension FastScan

Описание: The video is of a 1um, 512x512, 23Hz, scan of Celgard® taken with the Dimension FastScan. This demonstration is over twice as fast as the 10Hz video we showed previously, additionally we demonstrate the Celgard® with the mesh oriented a couple different ways, here shown perpendicular to the scan direction.

As you start to see different images and movies, there are a couple key things to look for: In the FastScan phase images you can see a couple important things. Each of the domains on the top surface is well defined. If a system is not tracking, or scanning beyond its limits, those features will look washed out. Another good indication of tracking is if the phase signal "tops-out". In the FastScan image at 22Hz, this is not a problem.

It's also good to look at the topography line traces. Sometimes, trace/retrace will not match. Often this can be corrected by simple optimization, and this in turn can lead to significantly faster imaging speeds. However, if it is coupled with the phase problems, then it is more likely an indication that the system is trying to image beyond its capability.

Also, in your evaluations be sure to include all of the criteria to be considered fast. The previous robust community discussion also recommended TipCheck and a Grating videos.
