* Dynamic Operating Current Coefficient in µA per Hertz and mrad. Example: Sinusoidal scan of 100 mrad at 10 Hz requires approximately 0.45 mA drive current.

** Value for aluminum top plate. Lower resonant frequency for other platforms due to higher moment of inertia: Titanium: +60%; Invar: +200%; steel: +190%.

*** Noise equivalent motion with E-503 amplifier.
