Leica TIRF, room 3604

This microscope is set up for live cell imaging and uses the property of total internal reflection to illuminate fluorophores within the evanascent field of the sample.

Information about the microscope

Total Internal Reflection Fluorescence (TIRF) microscopes llows efficient detection of fluorescence within regions close to the sample/glass interface with a high sensitivity, which minimizes the damage to living cells. The system offers three wavelengths: 488nm, 561nm, and 635nm; with fast AOTF control. Image acquisition speed can be increased to several images per second using the quad cube filter to avoid repeated mechanical filter changes. Various TIRF slice thicknesses are possible, depending on the excitation wavelength, as well as epifluorescence imaging.
