3D imaging devices, e.g. Laser Scanning Microscopy or Light Sheet Fluorescence Microscopy are most commonly stand-alone instruments of high technical potential, but limited flexibility. Therefore, there is some need of combining these techniques together with further methods, e.g. spectral imaging or fluorescence lifetime imaging, in a single low-cost instrument. Simultaneous detection of multiple parameters and increased resolution give additional information for diagnostics of living cells and tissues.
We developed two miniaturized modules, which are easily adapted to a conventional (inverted) microscope. The first module permits illumination by a light sheet with simultaneous adjustment of the detection system for 3D imaging at low light exposure to avoid phototoxicity and photobleaching. The second module permits rotation of the sample for multi-view imaging, axial tomography and finally an increase of resolution.
Potential manufacturers are welcome for their cooperation.
Prototypes are available and ready to use. For some types of microscopes mechanical adaptors are required.
The state of invention is disclosed and published. There are no pending patents.
