page
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.
1) Work environment
2) For hazard avoidance
3) For cantilever treatment
4) For inspection

Open the case
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.
It is recommended that precautions be taken to prevent damage to the
cantilever tips from electrostatic discharge.
Caution
See the specification sheet of OLYMPUS Micro cantilevers at the last page of this manual.

：
Clean bench
(Use of an electrical charge neutralizer of ionizer is recommended.)
：
Protective eye glasses
：
Tweezers (sharp pointed tip)
：
Thin stick like Toothpick, Both side adhesive tape
：
Anti-static mat
(Use of tweezers made of insulator is recommended.)
(Use of anti-electrostatic discharge mat and a wrist band is
recommended.)
：
Stereo microscope
Please handle our cantilevers carefully because they are fragile.

3) Wind both-side adhesive tape around the top of the thin stick to prepare an adhesive stick for
picking up the chips from the cantilever wafer
(BL-AC10DS-A2)
3. Tip View
This cantilever is shaped like bird-beak so that the tip is located at the very end
of the cantilever.
1. Short and thin 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.
2. Monolithic tip
The triangular portion near the cantilever free-end laps
under at an angle of 35 degrees and the corner of the
triangular portion behave as an actual probe with its
tip radius of 24 nm (typ.). The tip and lever are
monolithic so that tip-breakage around the interface of
tip and lever is avoidable.
4. Gold reflex coating
Gold is coated on the back side of the cantilevers for optical deflection sensing.
This small silicon-nitride cantilever is suitable for high speed AFM
measurement in water and shows high resonance more than 300 kHz (500 kHz
(typ.)) in water while it is soft enough for revealing soft bio samples (spring
constant 0.1 N/m (typ.)). It shapes in bird-beak, sized 9
m(L) x 2
m(W) x 0.13
m(T). It should be used in AFMs which deflection sensor illuminate cantilevers
with their laser spot less than 5
m in diam. (ideally less than 2
m).
