Simulation of STED microscopy

This application note demonstrates how our modeling software SimphoSOFT® allows a user to model and optimize the performance of STED using the SimphoSOFT features of multiple beams and stimulated emission. SimphoSOFT can be used

  • to help design STED microscopes, and
  • to optimize the performance of fluorescent probes used in STED microscopy.

STED setup

STED apparatus showing reduced spot size for fluorescence emission




STED Donut pulse

FWHM of the fluorescing spot will be greatly reduced at a time of 60 ps (after the Donut STED pulse has passed through the sample) compared to a time of 5 ps (which is just before the Donut pulse). More analysis and details are in the application note.


SimphoSOFT® can be purchased as a single program and can be also configured with Energy Transfer add-on ET add-on, Multi-Beam add-on Multi-beam add-on, Optimization add-on Optimization add-on, Z-scan add-on Z-scan add-on, and MPA Info+ add-on MPA Info+ add-on for an additional charge.
