We show that a pixelated lens with appropriate parameters exhibits an apodized point-spread function that originates in the finite size of the pixel’s pupil. We evaluate numerically the degree of apodization and the enlargement associated with the point-spread function in terms of the parameters that characterize the pixelated lens.
