AFM tips ETALON series without conductive or magnetic coating.
Chips and cantilevers of ETALON series cantilevers are manufactured from polycrystaline silicon, which allows for better controll of cantilever parameters (when compared to regulard cantilevers from monocrystaline silicon). This allows ETALON series to achieve low variance of resonance frequency (10% when compared to monocrystaline silicon tips) and force constant (20%). Monocrystaline tip is inserted into the polycrystaline cantilever, which means ETALON tips have the same tip diameter as polycrystaline silicon tips (guaranteed 10 nm) and have high aspect ration. There are two cantilevers on opposite sides of the chips with different resonance frequencies. Tips are also available with conductive or magnetic coatings.
