title: Design of a relay lens with telecentricity in a holographic recording system.
abstract: We reveal a doubly telecentric Fourier 4f relay for a holographic recording system. These lenses are made of Zeonex and their aspherical surfaces were formed by a diamond-turning machining. The total stroke of the system is 244.69 mm, including six lenses. The relay system provides a small distortion and the root-mean-square error of the wavefront within 1/4lambda (lambda = 532 nm). In addition, we describe the optical behavior of the designed system and present our experiences at manufacturing aspheric lens prototypes.
