The synergy between the new generation of Power HyD detectors, the completely optimized beam path, and the unique White Light Laser gives you perfected imaging performance. Your answers are clearer, derived from brighter signals, more contrast and astounding detail from even multiple low abundance labels. Our new Power HyD detectors provide you with:

  • Enhanced image quality: STELLARIS provides an ideal combination of brightness, resolution and contrast.
  • Complete spectral freedom:   Our next-generation White Light Lasers which allow a perfect match to the fluorochrome allows you to simultaneously use up to 8 single excitation lines from 440 nm to 790 nm.
  • Gentle Live Cell Imaging:  Preserve your sample’s integrity through efficient signal acquisition at the lowest required levels of illumination

STELLARIS includes our new and unique TauSense technology allowing you to extract a new dimension of information from every sample and increase the scientific impact of your research using lifetime-based data to explore the function of molecules in their cellular context.  Our new TauSense technology gives you access to:

  • New Dimension of Imaging:  TauContrast gives you immediate access to functional information such as metabolic status, pH and ion concentration
  • Improve Image Quality:  Maximize detection efficiency by removing unwanted autofluorescence while preserving the desired signal with TauGating
  • Multiplex Beyond Spectral Options:  Separate species with TauSeparation even when their emissions fully overlap

STELLARIS 5 delivers the very best of our platform. It is a completely re-imagined core system that sets a new standard for confocal microscopy. It is the only confocal system with an integrated WLL, combined with our proprietary Acousto-Optical Beam Splitter (AOBS) and new Power HyD S detectors. Together with the new and unique TauSense technology, STELLARIS 5 sets a new standard for the quality of images and quantity of information generated. This perfected imaging performance is easily attainable thanks to the smart user interface, ImageCompass, which guides you through your experiment set up and acquisition in an easy and intuitive manner.


STELLARIS 8 is a forward-looking system, offering all the benefits of the STELLARIS 5 core system plus added functionality thanks to an extended spectrum WLL and specialized detector options of the Power HyD family. This allows you to expand the range of confocal applications in your research. STELLARIS 8 can be combined with all Leica Microsystems modalities, including FAst Lifetime CONtrast (FALCON), Deep In Vivo Explorer (DIVE), and STED. STELLARIS 8 new features maximize the potential of these modalities and gives you the power and potential to set new standards for research.
