In this paper, we present a catadioptrie telecentric objective for a holographic recording system. The lens was made of Zeonex, whose aspherical surfaces were formed by diamond-turning machining. A least-squares method was used to solve a set of linear equations for the spot size of charge-coupled device (CCD). The data were obtained to generate an S curve, which was used in the pupil obscuration method, for the control of the system operated in a linear range of ± 0.3 mm.
