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 PMCL-AC200TS 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 PMCL-AC160TS 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.

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.
