Preparation
1) Please prepare the followings before using OLYMPUS cantilevers.
2) To gain a better understanding of how cantilevers and chips are connected, cantilevers

should be inspected under the microscope.
High mechanical Q factor of the cantilevers allows you high sensitivity measurement to

probe your sample surface gently.
3. Tip View – The tip is located on the very end of the cantilever.
This feature allows you to set the tip over a point of interest on the sample, easily and
precisely, if you use an AFM combined with an optical microscope.
4. Point terminated tip – The tip radius is typically 7nm
A sharpened tetrahedral tip of single crystal silicon is employed for high-resolution
measurements. The tetrahedral shape is ideal for achieving a point terminated tip. In
addition to the geometrical dimensions of the tip, the tip is further sharpened with our
exclusive sharpening process.
5. Symmetric tip – The tetrahedral tip is thin with the macroscopic tip angle of 35 degrees
viewing from both its front and side. Tip shows good symmetry in viewing along the
cantilever axis (see Chapter 5).
Symmetric shape tip results AFM images less distortion which reduce misinterpret of
the data.
6. No metal reflex coating
2. Pre-separated chip – Each cantilever chips is isolated in the case.
The chips can be attached to the AFM instrument as soon as the case is open.
7. Compatible chip – The thickness of the chip (substrate) is 0.3mm.
This type of the chip can be attached to most of AFM instruments.
2) For hazard avoidance
3) For cantilever treatment
4) For inspection

Caution
1) It is recommended that the cantilever case be opened in a clean environment like a clean bench
in order to avoid the cantilever being contaminated. Handling under an ionizer is recommended.
2) Avoid wearing clothes like woolen sweaters, fleece etc that give off the static electricity when

preferable.
3) In opening the case, put the plastic case label-side down on a desk.
