Alpha3 is a new generation of light sheet microscope addressing the needs of high temporal resolution along with spatial high-resolution to achieve qualitative and quantitative 3D imaging of fixed or live biological specimen.

From in-vivo imaging to large cleared samples, the Alpha3 microscope delivers unprecedented image quality while keeping the necessary flexibility and modularity expected for cutting-edge scientific research instruments.

Typical applications of Alpha3 include in toto imaging of small animal models such as whole mouse embryos, morphogenesis and embryogenesis of model organisms: C.elegans, Drosophila, Zebra fish, live imaging of cell cultures, functional imaging of neuronal activity, fluorescence imaging of marine organisms or plant developmental biology.
