Wide Field Microscope (Olympus IX81)

The Olympus IX81 is an integrated system for advanced wide-field fluorescence imaging and analysis. It is equipped with a sensitive CoolSNAP HQ2 CCD camera for high resolution fluorescent images. You have the option to use lasers to excite your sample to improve the sensitivity and reduce fluorescent background.  In addition the system is equipped with an objective Piezo for high precession and fast Z sectioning as well as a 2D-VisiFRAP Real-time Scanner for FRAP / Photo activation experiments.  In the wide-field transmitted light imaging mode, DIC is available on most lenses.

This system is perfect high quality fluorescence imaging were you need a good sensitivity and fast acquisition speed but confocality is not of importance.

  • Life cell or fixed sample imaging
  • Z sectioning
  • Time series capture
  • Co –localisation studies
  • FRAP / Photo activation


  • simple setup with very little preparation required
  • very sensitive
