- an SPM sample for fast and convenient determination of the AFM tip condition. TipCheck
offers a fast and easy way to compare and categorize different AFM probes with respect to tip apex shape and sharpness.
Check whether your tip is still good, starts showing wear or already blunted without the need of scanning an entire image or doing an SEM inspection!
Additionally, this sample works perfectly with Auto Tip Qualification and Tip Characterization software that is available on the market.
The following figures show a comparison between different probe tips used to image the TipCheck sample.
Scan size is 1 x 1µm for all images. Height scale is 100nm.

The TipCheck sample consists of an extremely wear-resistant thin film coating that is deposited on a silicon chip. This thin film coating shows a granular, sharply peaked nanostructure which makes it ideal for reversely imaging an AFM probe's tip apex.
The die size of the TipCheck is 5x5mm. It comes glued onto a metal disc so that it is ready to be placed into your AFM set.
