Multiphoton microscopy provides the greatest imaging depths in some of the most challenging samples, and demands highest sensitivity. With optical designs dedicated to providing the deepest penetration depths and light collection efficiency, the FV1200MPE Basic provides powerful tools for a wide range of applications. Configured with standard visible confocal capability and a range of descanned and non-descanned detector options, the MPE Basic is an ideal tool for core facilities and researchers with a broad range of research needs.
