About us

Genoa Instruments is a spin-off project of the Istituto Italiano di Tecnologia pioneering new technologies in the field of optical microscopy.
The company will develop and commercialize a new confocal microscope based on the Image Scanning Microscopy technique, which will allow to achieve both spatial and temporal super-resolution at the same time.
Our innovative optical module will constitute a new paradigm in the field of optical microscopy, potentially establishing as the next generation confocal microscope.
The microscope will be highly affordable and platform independent, allowing for tailored solutions as well as for the upgrade of existing widefield and confocal microscopes.



Image scanning microscopy (ISM) improves the spatial resolution of conventional confocal laser-scanning microscopy, but current implementations reduce versatility and restrict its combination with fluorescence spectroscopy techniques, such as fluorescence lifetime.
Our team implemented a natural design of ISM based on a fast single-photon detector array, which allows straightforward upgrade of an existing confocal microscope, without compromising any of its functionalities.
In contrast to all-optical implementations, our approach provides access to the raw scanned images, also opening the way to adaptive reconstruction methods, capable of considering different imaging conditios and distortions. Castello et al., Nat. Methods (2019).
