Total internal reflection in nature
The instant TIRF-SIM apparatus is built directly upon our previously reported iSIM system7, but with two important modifications in the excitation path. First, we used a 1.7-NA objective (Olympus; APON100XHOTIRF) for excitation and detection. For aqueous samples with a refractive index of 1.33, 1 – (1.33/1.7) = … See more We used two methods to estimate evanescent field depth. First, we used an analytical method26.
