Diffraction image of a point source due to an optical system with residual primary coma and nonuniform amplitude transmission is studied in order to obtain a suitable expression for the fractional encircled energy distribution in the Fraunhofer plane. Numerical results are obtained for a series of pupil filters and for various amounts of coma in the system. Intensity distribution, fractional encircled energy distribution, Strehl ratio, two-point resolution, and comatic elongation are the properties of the diffraction field that have been examined. A comparative study of the performance of these pupil filters under influence of primary coma is also presented.
