Interferometer Controller


For ultra-sensitive detection of cantilever deflections, fiber interferometry is a powerful technique. Nanonis has introduced an active feedback loop to control the gap between the fiber-end and the back surface of the cantilever, ensuring detection of the cantilever motion at the optimal working point of the interferometer signal.

  Highlights
  • Performs automatic calibration of cantilever deflection and piezo movement according to the wavelength of the laser
  • Adjusts the operating point automatically in order to optimize the sensitivity
  • Deflection measured either through the interferometer signal (open loop) or by the piezo movement (closed loop)
  • Compatible with Fabry-Pérot interferometer type.

Nanonis SO5/TSO 16-channel signal source released

The SO5 and TSO are 16-channel precision, low-noise analog output add on modules for the Nanonis SPM Control System and the Nanonis Tramea quantum transport measurement system. Nanonis Tramea users can profit from up to 48 temperature-stabilized 20-bit signal sources able to control even the most complex nanostructures. More information about the new instrument can be found here
