Paper Abstract

The size of the secondary mirror in a reflecting, on-axis telescope has three effects on the performance of the imaging telescope for detection of very faint objects in the vicinity of bright objects. First, the size, shape, and peak of the side lobes (including the zeroth side lobe) change with the size of the secondary mirror. Second, the amount of collected light decreases in proportion to the area of the secondary mirror. Third, the position of the first zero decreases, effectively increasing the resolution of the optical system as the secondary mirror increases in size. All three effects impact the optimum design of an imaging instrument used for detection of planetary systems around the nearby stars.
