In two-photon microscopy
WebMar 5, 2024 · In a DIC microscope, two beams of light are created in which the direction of wave movement (polarization) differs. Once the beams pass through either the specimen or specimen-free space, they are recombined and effects of the specimens cause differences in the interference patterns generated by the combining of the beams. WebSep 28, 2024 · For in-vivo two-photon microscopy, e.g. in neuroscience, fluorescent proteins in the range of 900-1100nm (GFP, RFP) are currently the common choice since the longer …

WebApr 1, 2000 · Similarly for the two-photon excitation case, the log-log plot of the initial fluorescence intensity versus power (open squares in Fig. 2 B) gave the expected slope for two-photon excitation (slope = 1.9 ± 0.2).However, the log-log plot of the fluorescein dextran photobleaching rate under two-photon excitation (710 nm) gave a slope of 3.1 ± 0.1 (filled … WebNov 15, 2024 · Since in two-photon microscopy the wavelength of the fluorescence light is roughly two times shorter than that needed for excitation, wide-band achromatic compound lenses have to be used so that two-photon induced fluorescence light can be efficiently collected. Achromatic lenses consist of multiple different materials combined in such a …
