The Multi Conjugate Adaptive Optics Relay (MAORY) for the European Extremely Large Telescope shall re-image the telescope focal plane for the client instruments installed on two exit ports. By means of natural and artificial (laser) reference sources for wavefront sensing, and of deformable mirrors for wavefront correction, MAORY shall be able to compensate the wavefront disturbances affecting the scientific observations, achieving high Strehl ratio and high sky coverage. The optical interfaces to the client instruments must replicate the telescope one while the volume allocation on the Nasmyth platform is under definition at the moment of this writing. We show the latest version of the optical design that matches the current requests and its optical performance. The laser guide stars channel, separated from the science path by means of a dichroic beam-splitter, is also presented.

ELT-CAM is the E-ELT rst-light instrument that associates MICADO, the near-infrared imager, and MAORY,its multi-conjugate adaptive optics (MCAO) module. ELT-CAM will also come with a single conjugate adaptiveoptics (SCAO) capability motivated by scientic programs for which SCAO provides the best AO performance(e.g. exoplanets, solar system science, bright AGNs, etc).This SCAO capability will be developed within MICADO through a dedicated SCAO module with its naturalguide star (NGS) wavefront sensor (WFS), allowing MICADO to work in a SCAO stand-alone mode withoutMAORY, and inside MAORY with the same dedicated NGS WFS. MICADO and MAORY consortia are workingtogether on the development of this SCAO capability in order to perform a WFS trade-o study between Shack-Hartmann and Pyramid, to optimize the design of the NGS WFS as well as the interfaces between the twoinstruments. We present here the current status of the work done by the two consortia on the implementationof this SCAO capability for MICADO and MAORY.

The MAORY adaptive optics module is part of the first light instrumentation suite for the E-ELT. The MAORY project phase B is going to start soon. This paper contains a system-level overview of the current instrument design.
