Medium and Stiffer Middle Silicon Probe (New concept chip)

NeOLYMPUS OMCL-AC series cantilevers are designed for AC mode AFM in air.       

OMCL-AC Series has a tetrahedral tip on the exact end of the cantilever.



Outstanding features of new Tetrahedral cantilever

Application for various sample surfaces:

The mid-range mechanical properties [resonance frequency: 150kHz, spring constant: 9 N/m (typ.)] mean that the OMCL-AC200TS-R3 is tailored to any surface from soft to hard.
The stiffer middle mechanical properties [resonance frequency: 300 kHz, spring constant: 26 N/m] means that OMCLAC160TS-R3 is redesigned for revealing sample surface precisely and gently.

Doped silicon cantilever:

The cantilever is made from silicon with a low surface resistance of 0.1 - 0.4 Ω?cm.
This means 1/20 resistance of our conventional cantilevers.

Acclaimed 'TipView' structure:

The probe can be easily positioned at the exact point of your interest. The probe is located at the exact end of the cantilever so that the probe apex is not obscured during optical observations.

Ideally point terminated probe:

The probe is tetrahedral, ideally point terminated. The probe apex 1 micron or more is further sharpened.

New concept chip:

The ideally parallel side-walls of the chip make tweezing easy and eliminate problems with chipping and debris.



Below are SEM images of a Tetra tip from the front and side, and the last is a magnified view from side.


Tip shape : sharpened tetrahedral (tilted)
It shows good symmetry viewed from the front and is inclined viewed from the side.
Considering this geometric feature, choose the fast scan (X) direction


Metal coating

[Reflex coating]

Thin aluminum film with the thickness of 100nm is coated on the cantilever for reflecting light from the deflection sensor in the AFM equipment. High reflex for high S/N sensing can be expected.
