Thank you for purchasing OLYMPUS Micro cantilever.
Please read this manual carefully before use.
- 1e -
Please obey the following to the OLYMPUS micro cantilevers
Warning
Use protective eye glasses when handling to avoid
damage to the eyes from breakage of the cantilever
chips.
Caution
Please handle our cantilevers carefully because they are fragile.
Caution
Do not drop or shake the cantilever case. Even when the cantilever
chips are contained in the cantilever case, the cantilevers may break
if the case is handled roughly or jarred.
Caution
It is recommended that precautions be taken to prevent damage to the
cantilever tips from electrostatic discharge.
Caution
When discarding, please obey the laws and regulations in your
country and/or your company. These cantilever are made from
silicon and gold.

1 Preparation
(OMCL-AC55TS-B3)
1) Please prepare the followings before using OLYMPUS cantilevers.
- 4e -
2) To gain a better understanding of how cantilevers and chips are connected, cantilevers
should be inspected under the microscope.
1) Work environment
1. AC mode cantilever – This type of micro cantilever is for AC (dynamic) mode AFM operation.
High mechanical Q factor of the cantilevers allows you high sensitivity measurement to
probe your sample surface gently. Cantilever base material employs highly doped silicon
with a surface resistance of 0.01-0.02 Ω・cm.
5. Tip View – The tip is located at the very end of the cantilever.
This feature allows you to set the tip over a point of interest on the sample, easily and
2) For hazard avoidance
3) For cantilever treatment
4) For inspection
2 Open the case
：Clean bench
(Use of an electrical charge neutralizer of ionizer is recommended.)
：Protective eye glasses
：Tweezers
(Use of anti-electrostatic discharge mat and a wrist band is
recommended.)
：Stereo microscope
2. MegaHertz range cantilever – Resonance frequency of this cantilever is over 1 MHz.
The high resonance frequency with 1.6 MHz (Nom.) enables fast scanning measurement.
It can be used at SPMs which bandwidth of the sensor circuit is 2.5 MHz or above.
3. Low thermal noise
Low thermal noise of cantilever vibration attributed to its high resonance frequency and
high spring constant enables high resolution measurement.
precisely, if you use an AFM combined with an optical microscope.
6. 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.
7. Reflex coating cantilever – Gold is coated onto the back side of the cantilevers for
optical deflection sensing.
Good S/N signal can be expected in the optical sensor circuit.
4. 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.
8. Compatible chip – The thickness of the chip (substrate) is 0.3mm.
This type of the chip can be attached to most of AFM instruments.

Please handle our cantilevers carefully because they are fragile.
Caution
It is recommended that precautions be taken to prevent damage to the
cantilever tips from electrostatic discharge.
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
handling the cantilever cases and chips. Use of an anti-electrostatic mat and wrist band is
preferable.
3) In opening the case, put the plastic case label-side down on a desk.
The cantilevers are tip-side-up as viewed in the case.

The apex of the tetrahedral tip becomes sharper due to an oxide sharpening process. The
tip angle around a few hundreds nano meter down from the apex, is about 15 to 25
degrees (see below).

As can be seen in the left illustration, a
tetrahedral tip is located at the exact end of
the cantilever.
The finite tip shape will determine the scan
line profile as in the illustrations below.
The tip profile is symmetric with a half tip
angle of 18 degrees macroscopically (see left
below).
The side tip profile is asymmetric with a tip
angle of 35 degrees. Then the cantilever chip
is attached to a chip holder in your AFM with
an angle, about 10 degrees, the asymmetry is
improved (see right below).
