Total Internal Reflection Fluorescence (TIRF) Microscopy

WebThe production of an annular ring of light with a variable diameter has applications in laser material processing and machining, particle manipulation, and corneal surgery. This can readily be accomplished using a positive and negative axicon pair. However, negative axicons are very expensive and difficult to obtain with small diameters. In this paper, we … WebPerfecting TIRF optics Increasingly popular, total-internal-reflection-fluorescence (TIRF) microscopy systems prefer lasers for excitation because of their spectral purity and brightness. But the use of lasers can restrict other TIRF system components. Clearing these hurdles requires some careful considerations. Figure 1. WebPositive m < 1.
