The KolibriSensor™ from SPECS represents a new quartz sensor on the market that excels in its performance and its reliability. The spectral deflection noise density obtained with the novel external KolibriPreamp is below 1 fm/√Hz. This is a key advantage of the KolibriSensor™ , which results in faster acquisition and higher resolution. Even with the high spring constant of 540 kN/m, the KolibriSensor™ has a signal-to-noise ratio an order of magnitude better than tuning forks while the frequency shift per force gradient is of the same order as a typical tuning fork.
