Aimed at high resolution, an asymmetric point spread function has been obtained with good and bad sides by introducing three level asymmetric pupil functions. The good side has decreased side lobes while the bad side has increased side lobes. The asymmetry has been found to increase with the width of the edge strips within the slit aperture. On the other hand, there does not appear dependence of the asymmetry of the point spread function on the degree of amplitude apodization. But the magnitude of reduction of optical side-lobes is found to increase to a great extent by the amplitude apodization.
