WebMultiphoton excitation microscopy at 730 nm and 960 nm was used to image in vivo human skin autofluorescence from the surface to a depth of approximately 200 microm. The emission spectra and fluorescence lifetime images were obtained at selected locations near the surface (0-50 microm) and at deeper … WebAlso known as non-linear multiphoton, two-photon laser scanning or simply two-photon microscopy, it relies upon the principle of two-photon absorption. ... Traditional fluorescence microscopy uses a single photon to excite fluorescent dyes using mainly visible excitation wavelengths (390-700 nm). After excitation the electron will drop back ...
Two-photon absorption (TPA or 2PA) or two-photon excitation or non-linear absorption is the simultaneous absorption of two photons of identical or different frequencies in order to excite a molecule from one state (usually the ground state) to a higher energy, most commonly an excited electronic state. Absorption of two photons with different frequencies is called non-degenerate two-photon absorp… WebMultiphoton Excitation Microscopy (MPE) Widest Product Range Lasers for all multiphoton imaging modalities and any possible combination of probes and label-free...
