Abstract

MAORY (Multi Conjugate Adaptive Optics RelaY) is an adaptive optics module able to compensate the wavefront disturbances affective the scientific observation. It is one of the four instruments approved for construction at the ELT and will be installed on the straight-through port of the telescope Nasmyth platform. Due to the size of the optical elements and the instruments itself, a careful evaluation of the optical effects related to the thermal inhomogeneity inside the instrument must be performed. The status of the analysis, the proposed validations, and the solutions proposed to mitigate these effects are presented in this work.
