M45 - Viventis LS1 light sheet
System description
M45 is the microscope of choice for delicate living samples. It is suitable for long-term (several days) imaging of organoids, embryos and spores.
A sheet-shaped light beam is used for exciting a single plane of the sample. The fluorescent light from the excited plane is imaged by perpendicular, camera based detection. This results in optical sectioning with low-dosage excitation and next to no phototoxic stress for living samples. Only in-focus volumes that are actually imaged, are illuminated.
The LS1 is designed with inverted microscope geometry. The microscope allows dual-side illumination with a light sheet generated by scanning a gaussian beam. Three switchable light sheets with thicknesses of approximately 1 μm, 2 μm and 3 μm are available. The imaging compartment can host a dedicated sample carrier for multiple samples.
