When imaging a sample surface by AFM, it may be difficult to know whether the surface is imaged accurately or if it is affected by a blunt or broken tip. Blunt or broken tips will dramatically distort measurements like surface roughness or feature dimensions. To be certain that a proper AFM tip is used, they must be renewed regularly or checked via imaging in the SEM; both methods are time consuming and expensive.

The solution to this is to use the "Tip Check" sample for quick and convenient determination of the AFM tip condition.  A single scan is often enough to clearly show the condition of the AFM tip; "Tip check" offers a quick and easy way to compare and categorize different AFM  probes with respect to tip parameters like apex, shape and sharpness. 

You can easily check whether the the AFM tip is still good, starts showing wear, or is blunt or broken without the need of scanning an entire image or performing an SEM inspection of the tip. Additionally, the "Tip Check" sample works well with Auto Tip Qualification and Tip Characterization software currently available on the market.

The "Tip Check" sample consists of an extremely wear-resistant thin film coating deposited on a silicon chip. The thin film shows a granular, sharply peaked nanostructure which is ideal for reverse imaging of the AFM probe tip apex. The die size of the "Tip Check" is 5x5mm; it is mounted with electrically conductive epoxy resin on a 12mm metal  AFM disc.
