The FV1200MPE TWIN is the ultimate confocal and multiphoton system for optogenetics, electrophysiology and high speed measurements in live tissues. With dual IR laser inputs, an increase of 50% in multiphoton excitation efficiency and superb MPE dedicated objectives, the FV1200MPE TWIN delivers high sensitivity and deep imaging with the ability to simultaneously image and stimulate with both pulsed IR and visible lasers. Configured with standard visible confocal capability and a range of descanned and non-descanned detector options, the FV1200MPE twin pushes the envelope for interactive visible and multiphoton imaging.
