Outstanding Features of Tetrahedral Cantilever
Application for various sample surfaces :
The mid-range mechanical properties [resonance frequency : 150 kHz, spring constant : 9 N/m (typ.)] mean that the PMCL-AC200TS is tailored to any surface from soft to hard.
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.

Tip shape : sharpened tetrahedral ( tilted )
It shows good symmetry viewed from the front and is inclined viewed from the side.
Dimension of Levers and Chip (Substrates)
Metal Reflex Coating
Thin aluminum film with the thickness of 100 nm 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.
Packaging: Pre-separated chips
