Additional techniques

The system provides a STED 3X module for STimulation Emission Depletion super-resolution with 3 depletion lines. The module can improve both the lateral and axial resolutions beyond the Abbe’s limit of standard fluorescence microscopy.

Thanks to the tunable excitation, the system can reconstruct both the emission and excitation profile in a so-called Λλ mode. This allows a characterization of autofluorescence properties of a sample and the spectral unmixing of dyes with strong overlap.

In addition to standard galvanometric scanners, a resonant scanner coupled with a piezoelectric z-stage allows very fast recording (30fps and higher) of bright stainings in live cells. An Autofocus module guarantees the stability of the focus position.

The system also provides Single Molecule Detection (SMD) capabilities, with two Hybrid photon counting detectors and dedicated acquisition hardware. This module has a very broad range of applications, from FLIM/FRET experiments to microenvironment quantification of pH and ion concentrations in live cells, to the binding and conformational properties of molecules in FCS modalities.
