Figure 3

Intensity of 658 nm light forward scattered from a 1.35 μm diameter polystyrene bead in water (nwater=1.333) versus distance from the glass substrate (nglass=1.515). TIR wave penetration depth δp = 500 nm (θ=62.0°). (A) Solid line indicates results of our simulations, while dotted line with square markers (red in online version) represents experimental data.25 (B) Simulations of optical power observed by objectives with varying NA. Power is normalized to the maximum intensity observed when the bead is effectively in contact with the surface.
