Cutting edge technology to study nanooptical phenomena

The new NanoWizard® NanoOptics head comes with excellent physical and optical access to the sample from top and bottom as well as from front and side, even when the head and condenser are in place. Additionally, it has an integrated port for fiber SNOM applications.

Because stability and reproducibility of the SPM-tip positioning and scanning are vital for applications requiring the collection of single photons over a long time period, the system has been optimized for it. Improved closed-loop control on 5 or 6 axes and highest scanner resonance frequency in z deliver a scanner performance previously not available in a commercial AFM. This ensures highest data quality for imaging and force measurements in air and liquids.

The new Vortis™ Advanced SPM controller delivers cutting edge values for noise levels, data acquisition speed, and maximum versatility. Advanced electronics and software for multiple feedback controls, highest bandwidth and access to all signals combined with the ability to work with user-written scripts are all key elements for successful experiments. Synchronization of AFM and spectrometer data is achieved by a user-friendly software interface.

The NanoWizard® AFM is designed for optimal use in liquid and comes with a vapour barrier, encapsulated piezos and a variety of dedicated liquid cells. The system may also be used in air or controlled gas environments.

Flexibility in the software and the range of accessories make the system ready for any user-defined experiments. The newly developed fiber coupled detection module for sensitive detectors such as APDs and PMTs delivers outstanding results in terms of stray-light suppression.

Optical near-field experiments

Aperture fiber SNOM experiments
An integrated fiber SNOM port in the NanoWizard® NanoOptics head and the Tuning Fork module allow hassle-free integration of techniques.

Scattering-type SNOM (sSNOM) experiments
The new system is perfect for tip-enhanced applications such as fluorescence with nano-antennas made of nanofabricated or chemically modified tips. As an alternative to cantilever based optical probes, STM tips can be used with the new Scanning Tunnelling Microscopy (STM) module.

Nanomanipulation in optical fields
The new system is ideal for studying optical surface properties of dyes and markers, quantum dots/rods or metamaterials such as quenching or plasmon generation in combination with topography, nanomechanical, electrical and magnetic properties. Thanks to the symmetric design of stage and head as well as the latest closed-loop scanner technology in a 5- or 6-axis configuration, long-term stability and reproducibility reach the highest possible level.

Advanced fluorescence techniques and Time Correlated Single Photon  Counting (TCSPC)

Complementary techniques to AFM, such as epi-fluorescence, confocal laser scanning microscopy, TIRF, FRET, FCS, FLIM, FRAP, STORM, PALM, STED, spinning disc, etc., give insight about the behavior or location of particular features.

It is now possible to routinely combine AFM imaging and force measurements with these optical methods on the same sample spot simultaneously.
