The Ultima IV is a fully automated upright microscope – objectives are above the stage. This configuration is ideal for in vivo imaging of whole specimens. The Ultima IV is equipped with a tunable two ...

Two-photon excitation (TPE) microscopy enables imaging of living tissues up to a depth of one millimeter, which is 6 to 10-fold deeper than with confocal microscopy. Like confocal microscopy, TPE ...

Before uncaging, cellular fluorescence was negligible; during continuous two-photon excitation at 790 nm, we detected no photolysis, but two-photon uncaging at 730 nm selectively activated HCCC2 ...

Single-photon emission is a well-explored process. But in recent years interest in two-photon emission has ... Semiconductor devices also allow electrical excitation, which is more efficient ...
