The Wolfson Bioimaging Facility has 6 widefield microscopes offering routine fluorescence and transmitted light imaging alongside advanced applications including ratiometric analysis (e.g. FRET, calcium imaging), multi-well imaging and deconvolution

In widefield microscopy cameras are used to capture images equivalent to the view down the microscope eyepieces. When the additional features of more advanced imaging techniques such as CLSM (e.g. improved axial resolution and region of interest scanning) are not essential, use of widefield microscopes should be considered as they are easier, quicker and cheaper.


All our widefields (except widefield 4) have:

  • inverted microscopes with some DIC and phase contrast lenses
  • sensitive monochrome cameras
  • incubators for temperature control
  • CO2 enrichment if required for live cell imaging.

Widefield 1 has a DV2 Multichannel imaging system which allows simultaneous capture of CFP and YFP or GPF and mCherry.

Widefield systems 2, 5, 6, and 7 all have motorised stages for multi-site imaging.

Widefield systems 4 and 5 both have colour CCD cameras (Widefield 5 also has a monochrome CCD camera on a separate port).

Widefield systems 5, 6 and 7 have adaptive focus control to correct for focus drift during time-lapse imaging.


System name and detailsRoomFurther information

Widefield 1

Only widefield system that allows rapid switching of both excitation and emission wavelengths for flexible and rapid live cell imaging.

Now has DV2 Multichannel imaging system which allows simultaneous capture of CFP and YFP or GPF and mCherry.

It has two cameras - one more sensitive and one with larger field of view.
