The Total Internal Reflection Fluorescence (TIRF) technique is the ideal method for observations of cells close to the coverslip surface. By total reflection of the excitation light (typically laser) at the coverslip / medium interface, the fluorescence emission is limited to a very thin space in the vicinity of the glass surface. The resulting fluorescence images exhibits extremely high contrast and resolution with the possibility of real-time imaging of cell membranes, actin filament behavior or single molecule tracking.
The ORBITAL-200 system is even more flexible. It can combine in one chassis Ring-TIRF, 2D FRAP and widefied.
