The digital holographic microscopy system includes an optical table with active vibration damping and a modular inverted optical microscope with accessories for performing an interferometric layout for digital holographic microscopy. The optical microscope is fully motorized and allows, through two platforms, a direct access to the optical path and thus the possibility of external extensions with different optical systems. Basically, optical microscopy enables bright field microscopy with Köller illumination, phase contrast and differential interference contrast microscopy, epifluorescence microscopy and polarization microscopy. The optical microscope accessories include a wide range of optical lenses, optical adapters and adapters for fixing various samples. The extension for digital holographic microscopy includes two high-coherence laser systems, a wavefront modulation system, a scanning system and modular optical components for optical path adjustment, and the implementation of interferometric systems on an optical table.
