Two-photon light sheet microscopy (2P-SPIM)

Two-photon light sheet microscopy (2P-SPIM)

Multiphoton fluorescence microscopy has proven invaluable for tissue studies with its ability to provide 3D micron-scale resolution in thick/live samples. However it is a point-scanning technique, which limits its imaging speed to a few images per second (typ. 10^5-10^6 pixels/second). Multiphoton light-sheet imaging is emerging as an efficient method to achieve 50-100x faster two-photon imaging of thick tissues, with the additional benefit of strongly reducing photobleaching.
