Web1. Install the pulsed femtosecond NIR laser. 2. Build the external optical pathway from the laser source to the laser-scanning microscope with the optional spatial filter and the Pockels cell. 3. Modify the scanning unit of a confocal laser-scanning microscope for scanning by the IR beam from the external laser source. WebTwo-photon microscopy allows image acquisition in deep areas within tissues and organs. The operational principle of 2p microscopy is based upon the quantum physics of superposition, namely, the energies of two photons (and hence their wavelengths) are summed. For fluorescent microscopy, the implication of this experimental fact is dramatic. WebTwo-photon excitation (TPE) microscopy 1 has evolved as an alternative to conventional single-photon confocal microscopy and has been shown to provide several advantages. These include three-dimensionally resolved fluorescence imaging of living cells deep within thick, strongly scattering samples, and reduced phototoxicity, enabling long-term imaging … r elbow sprain icd 10
