Abstract
The Multi Conjugate Adaptive Optics RelaY (MAORY) is the Multi-Conjugated Adaptive Optics (MCAO) module for the European Extremely Large Telescope (ELT). MAORY is one of the ELT first light instruments, designed to feed the Near Infrared Red (NIR) camera MICADO with both MCAO and Single-Conjugated AO (SCAO) operation modes. The optical configuration provides a one to one image of telescope focal surface on the MICADO focal surface (with the additional capability for a second port dedicated to a future instrument), and allows the implementation of two deformable mirrors together with the Laser Guide Star (LGS) and Natural Guide Star (NGS) channels for wavefront sensing and tomographic reconstruction. In this paper we present the status of the optical configuration in the Preliminary Design Review (PDR) framework for the main path optics and the analyses results on the expected optical performance.
