Hello,

I measured the deflexion sensitivity with a variety of probes (from 0.32 to 50 N/m) on glass and sapphire surface and I am getting values in the range of 10 to 15 nm/V.

Isn't that a little low?

Thanks,

Benoit.

Hi Benoit,

The deflection sensitivity of a probe does change depending on the particular AFM system you are using (different photodetectors) and depending on whether you are in fluid or air. If you are using a Bruker AFM with NanoScope software you should have access to a probes database that will give you a nominal deflection sensitivity for a particular probe for the system you are using as well as for air or fluid.

With respect to the values you stated I find similar values on my BioScope Catalyst.

Best,

Andrea

Hello Andrea,

I am using a BIoscope catalyst with Nanoscope 5.

Where can I find this database?

Thanks,

Benoit.
