WebMay 26, 2024 · Two-photon excitation microscopy (2PEM), also known as multiphoton excitation microscopy, is a fluorescent imaging technique that allows deep imaging of living tissues. Two-photon lasers use near-infrared (NIR) pulse lasers that are less invasive and permit deep tissue penetration. WebJul 11, 2024 · Two-photon excitation microscopy is a particularly microscopy technique based on the capability, under specific circumstances, to excite with two photons one electron in the ground state. The particularity of this phenomenon concern the fact that the light used to induce the excitation has a lower wavelength than the collected fluorescent.
