Microscope Multiphoton Imaging Analysis

Multiphoton Microscope

In live cells and tissue imaging, a key technology is two photon laser scanning microscopy (TPLSM). It minimizes phototoxic effects and offers the possibility to image deep into tissues. A set of instruments using this powerful technology is available in the Imaging Facility at School of Pharmacy.

Key Features

Simultaneous excitation imaging with two-wavelength IR laser

Deep in vivo imaging with super high-sensitive GaAsP NDD

Ultrahigh-speed imaging of up to 420 frames per second
Multi-color in vivo imaging

Deep specimen imaging with non-descanned detectors (NDD)

Nikon's high-NA objectives are ideal for multiphoton imaging

Auto laser alignment when changing multiphoton excitation wavelength

Two types of scanning head enable high-speed, high-quality imaging

NIS-Elements C acquisition and analysis software
