Olympus AC160TS-R3 AFM tip.

Outstanding features of the OTESPA-R3 visible apex tip:

1) Easily access where you want to see:
The visible apex tip is located on the very end of the cantilever. This allows you to set the tip over a point of interest on the sample, easily and precisely, especially if you use an AFM combined with an optical microscope such as the BioScope Catalyst.

2) High lateral resolution:
A sharper tip is required for revealing a sample surface much more precisely. Tetrahedral shape is ideal for obtaining a point terminated tip. Actually, the radius of the curvature of the visible apex tip is very small and the average is less than 10nm even with the Aluminum reflexcoating.
The OTESPA probes cover a wide range of applications,however, it is outstanding in the observation of crystal surfaces, thin film, IC devices and so on. 3) Observation of rugged samples:
The tip is thin with the tip angle of 35 degrees. So this tip enables you to observe a narrower part of the sample.
Furthermore, the visible apex tip is a tilted tip, so substantial tip angle decreases more when it is attached to a chip holder in your AFM with certain tilt angle (probably, 5 to 20 degrees).  The tip is effective for observing rugged samples.
