TIRF - Total Internal Reflection Fluorescence

Advantages of the TILL-TIRF/Imaging System

• Switching between epifluorescence and TIRF illumination without any moving parts. The merging occurs where the beams do not overlap, i.e. at a plane conjugated to the back focal plane of the objective lens. The novel optical design merges two beams without sacrificing illumination efficiency and freedom of wavelength choice.
• Fast switching between epi and TIRF illumination (< 20ms)
• Homogeneous illumination over the entire camera chip
• Easy alignment
• Turn key system
