| Реферат: | eng: We present a procedure to precisely align lens elements using specific diffractive optics with an integrated transmission flat (Diffractive Fizeau Null Lens, DFNL) which serves as reference surface for a Fizeau interferometer. The method is used for aligning the optical assembly of the near-infrared spectrometer and photometer of the Euclid space telescope, which is currently being developed in the framework of the ESA Cosmic Vision 2015 - 2025 Program [ 1,2]. Each lens has a corresponding annular zone on a multi-zonal computer-generated hologram to control its position. The alignment sensitivity is well below 1 mu m. The achieved alignment accuracy of the lenses relative to each other depends mainly on the long-time stability of the integration tower. Error budgets of the utilized computer-generated holograms and physical limitations are analyzed. Calibration measurements and the typically reached alignment accuracies are shown and discussed. |
