4Pi-Confocal Imaging in Fixed Biological Specimens [PDF]

Biophysical Journal, 1998
By combining the wavefronts produced by two high-aperture lenses, two-photon 4Pi-confocal microscopy allows three-dimensional imaging of transparent biological specimens with axial resolution in the 100-140-nm range. We reveal the imaging properties of a two-photon 4Pi-confocal microscope as applied to a fixed cell.
