WebJul 7, 2024 · To create high-resolution, 3D images of tissues such as the brain, researchers often use two-photon microscopy, which involves aiming a high-intensity laser at the specimen to induce fluorescence ... WebSep 21, 2024 · We implemented the 3D ray-tracing method to the two-photon tomography of deep biological samples. That is, we developed an AO 2PE microscope by extracting the pupil position of an objective lens using relay optics in the excitation laser’s optical path of the two-photon microscope system and placing an SLM at that position .

WebThree-photon microscopy (3PEF) is a high-resolution fluorescence microscopy based on nonlinear excitation effect. [1] [2] [3] Different from two photon excitation microscopy, it uses three exciting photons. It typically uses 1300 nm or longer wavelength lasers to excite the fluorescent dyes with three simultaneously absorbed photons. 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.
