PHI
The PHI is the ultimate plug-and-play
adaptive optics platform for microscopy.
PHI is Phaseform's solution to enable a seamless integration of adaptive optics to any microscope via the microscope's camera port. It contains a Deformable Phase Plate (DPP) located at the microscope’s pupil plane for precise aberration corrections. It additionally features an integrated tunable lens for ultra-fast remote focusing.
