Laser Sources for Microscopy Systems
LIGHT CONVERSION product portfolio with recently released microscopy-dedicated femtosecond laser sources, CRONUS-2P and CRONUS-3P, covers applications in functional neuroimaging, optogenetics, and deep imaging using medium-repetition-rate three-photon excitation and fast high‑repetition-rate two-photon imaging, as well as widefield and holographic excitation using high-power laser sources. See the CRONUS series comparison table below, while the complete list of laser sources for nonlinear microscopy and examples of the state-of-the-art applications are available in our latest brochure.
