Remarks
This microscope acquires images with improved axial resolution compared with more coventional widefield microscopes.The newest TauSense technology gives instant access to lifetime-based information, delivering additional insights to your experiments. In addition to the multicolor images in fixed samples the microscope can acquire large tile scans fully automated thanks to the LAS X Navigator.
