Olympus OMCL-AC240TM-R3

OSCM-PT-R3 series probes have platinum-deposited cantilevers that aresuitable for conducting scanning probe microscopy in air usingelectric force microscopy (EFM) or Kelvin probe force microscopy (KFM) modes, with an unprecedented sharpness of 15nm radius as a metal coated probe.

These probes feature:

1) High electrical conductivity:
The platinum-deposited probe shows lower conductivity in one and a halforders of magnitude than that of highly doped silicon probes. Its probe resistanceof 350 ohms is sufficiently low for electric measurements required highelectro-potential resolution. The surfaces of precious metal coatingsare free from oxidization and are electrically stable.

2) High resolution:
The apex of 15 nm (typ.) radius is prominently sharp among metal-coated probes (see the tip apex). The thin and sharp tetrahedral probe reveals sample surface precisely both in electrically and in topographically.

3) Visible apex tip:
OSCM-PT-R3 has a tetrahedral tip on the exact end of thecantilever. Since the tip isn't hidden by the body of cantilever, it canbe positioned exactly at a point of interest using an opticalmicroscopy.

Cantilever Specification
OSCM-PT-R3 Cantilever Image
Aluminum reflective coating on the backside of the cantilever. The Al Reflective coating increases the laser signal (A+B) by up to 2.5 times. Although not necessary for general imaging, reflective coating is recommended for thin cantilevers, highly reflective samples, and machine vision applications.
