Abstract

The deformable mirror are one of the key parts of MORFEO instrument when the system is working as multi conjugate wavefront corrector. However its stability is fundamental to guarantee a low wavefront error at the level of the MICADO focal plane when MICADO is acting in SCAO mode. In this paper we present our WFE constrains, the strategy and the analysis we performed to eventually guarantee the system inside the thermal specification stability.
