Product Description:

***Note: Bruker has launched an improved MESP-V2probe and recommends customers transition to this new probe model.  Thelegacy MESP is still available while supplies last, at which point it will become obsolete.

Bruker's MESP is the established choice for Magnetic Force Microscopy.  Built on the high-performance FESP AFM probe, the hard Cobalt-Chromium coating on this tip is tailored for high-sensitivity and magnetic contrast.  This cost-effective probe has a nominal tip radius of 35 nm for excellent lateral resolution for MFM, as well as other electrical and capacitance applications requiring a cantilever with conductive coating. 

The MESP has a nominal coercivity of 400 Oe (medium), and a magnetic moment of 1e-13 EMU (medium). 

The reflex side of the cantilever has a Co-Cr coating for increased reflectivity up to 2.5 times that of an uncoated probe.
