-Is it compatable with the nanoscience preamp model# BT00536?
-What is the electrical connection on the probe to excite the tuning fork (pin out of 3 pads on assy)?
-What is the typical resonance frequency and drive voltage?
1. I am not familiar with said amplifier. But in general it depends on how you wire things up. There are several strategies on how to excite, e.g. mechanical, electrical and amplify tuning forks, e.g. transimpedance amplifer, voltage amplifier, differential amplifier and depending on your choice you may have to collect your components properly.
2. There is no connection to the probe. The 'probe" is the NSOM tip. The tuning fork is simply the sensor measuring the movement of the probe. Two of the three pads are connected to the opposing electrodes on the fork, the third pad is open and can be custom wired for e.g. making an electrical connection to the probe for combined electrical/optical measurements.
3. The resonance of the bare fork is 100 kHz. In the final assembly with the NSOM tip the resonace drops a bit but is still >90kHz. As we operate the setup via mechanical excitation the drive voltage depends strongly on the dither piezo used and the efficiency of the coupling, mainly the springs used to hold the assembly down. In the Aurora-3 around 20--40mV drive typically resulted in around 2nm tip amplitude.
