Microscopy developer Mesolens Ltd. has adopted Prior Scientific Ltd.’s precision stages and focusing systems for its microscope system. The Mesolens microscope images relatively large, biomedically important specimens such as embryos, brain areas or tumors with full 3D recording of thousands of cells. The microscope’s design includes a novel apochromat lens with a numerical aperture to magnification ratio far in excess of conventional lenses used by other microscope manufacturers. The low magnification with exceptionally high numerical aperture lens can image an entire specimen while retaining sub-cellular detail throughout the entire specimen, removing the need for image stitching. Prior Scientific's control system, motorized stage and focus motor are used in the system. The focus motor enables the Mesolens microscope to provide highly accurate imaging in the Z axis. Edge repeatability and precision ensures that the correct position of the specimen is obtained and maintained throughout the entire imaging process.
