A triangular silicon nitride probe for faster WaveMode imaging and for CleanDrive dynamic mode, with a metal coating tuned for photothermal excitation. It reaches resolution down to atomic structure and suits nanomechanical work on stiffer samples such as soft metal alloys.
A silicon nitride probe for photothermal off-resonance tapping in WaveMode, with a gold coating on the reflex side tuned for photothermal excitation. The paddle shape limits reflective interference from the sample and raises the sum signal. It works in air and in liquid.
The CHI200(B) is a picoamp booster and Faraday cage that lets current down to a few picoamperes be measured. It places the preamplifier close to the electrode for lower bias current and noise, and the cage also suppresses mains frequency interference. Detection and switching are automatic.
