WebOct 17, 2014 · It requires a million times more photons to impinge upon a single acceptor molecule within a 10-18 second interval than is necessary in single-photon fluorescence microscopy. The light source of choice is thus an ultrafast, high-powered, mode-locked (pulsed), tunable cavity Ti:sapphire laser, which can cost $180,000 or more. WebMar 5, 2024 · Currently, use of two-photon microscopes is limited to advanced clinical and research laboratories because of the high costs of the instruments. A single two-photon microscope typically costs between $300,000 and $500,000, and the lasers used to excite the dyes used on specimens are also very expensive.
