Abstract

We present in this report the design of the atmospheric dispersion compensator for the adaptive optics system of DAG, the new 4 m Turkish telescope. An Amici configuration has been chosen, made of a pair of doublets prisms, located on both side of the tip-tilt mirror of the system’s pyramid wavefront sensor. Our design methodology, using a Python controlled ZEMAX model, is described, with our results, as well as the design of a triplet lens to compensate for the remaining pupil nutation.
