AXIAL HOLOGRAPHIC MICROSCOPE FOR PHASE VISUALIZATION

SKU0003
DESCRIPTION

Digital phase-shifting holography allows for the reconstruction of both amplitude and phase of the wavefront by recording the interference field. The device includes a lens with a geometric phase effect that helps split the incoming radiation into two beams, introducing phase delay and changing polarization. The microscope uses a polarization camera equipped with an array of micropolarizers at different polarization angles, which is coupled with an array of pixels on the camera. This allows for simultaneous
recording of multiple interferograms with different phase shifts in a single exposure. Additionally, the device allows the use of low-coherence light sources for capturing digital holograms. The use of a single-arm interferometric setup ensures the device’s resistance to external mechanical vibrations.

CHARACTERISTICS

The lateral resolution of the microscope for optically transparent micro-objects is no less than 1 µm.
