TNNSG Series Semicontact Mode AFM probes with Conductive Coating

High Resolution Silicon AFM Cantilevers TNNSG series are designed for electrical modes which operate with the probe in intermittent contact with the surface. The cantilever has a gold reflective coating on the top side to maximise the laser signal. The conductive coating on the tip side can be gold or platinum- iridium with a thickness of 20-30nm
