The LaVision BioTec UltraMicroscope II light sheet microscope combines macro-imaging capabilities with cellular resolution and allows 3D imaging of cleared samples in aqueous and organic buffers. The UltraMicroscope provides the perfect complementary microscopic technique to macro in vivo techniques like Bioluminescence Imaging (BLI), Single Photon Emission Computed Tomography (SPECT) and Magnetic Resonance Imaging (MRI).
The optical principle of the UltraMicroscope is known as SPIM (Selective plane illumination microscopy) or LSFM (Light Sheet Fluorescence Microscopy). It allows high resolution, excellent optical sectioning and high speed imaging. The UltraMicroscope II is the only system that connects these features with macroscopic sample dimensions up to 1 cm³ or larger.

Researchers who need artefact-free data from an overview to a specific region of interest with cellular resolution apply ultramicroscopy in their work. For example, neuroscientists focusing on the regeneration potential of neurons and the axonal pathfinding use this system as do oncologists verifying the efficiency of neovascularization inhibitors. In the field of immunology, lymph nodes and the developmental steps of entire lymphatic system are analyzed. The different developmental stages of animal models can be imaged for phenotyping or characterization of pathologies. Image acquisition made in vivo as well as the imaging of samples prepared by any clearing procedure are possible. Tissue with endogenous fluorescent proteins like GFP or stained with labelled antibodies can be analyzed quickly and easily with this setup. Clearing procedures like 3DISCO and CUBIC have been developed with the UltraMicroscope.

TriM Scope II
Two-photon excitation microscopy is a fluorescence imaging technique that allows imaging of living tissue up to about one millimeter in depth. Being a special variant of the multiphoton fluorescence microscope, it uses red-shifted excitation light which can also excite fluorescent dyes.
