When imaging biological samples it is commonly assumed that the point spread function of the microscope is not perturbed by the sample itself. Quantitative phase imaging studies indicate that typically studied cells can induce strong phase shifts, sufficient to disturb the complex point spread function. Even a relatively small phase shift of half a wavelength can completely change the point spread function of a multi-beam microscope. Here we propose a method to render the point spread function insensitive to sample-induced phase shifts.
