MAVIS: FDR mechanical design of the adaptive optics module

Le résumé fourni par la source

MAVIS (MCAO Assisted Visible Imager and Spectrograph) is a Multi-Conjugate Adaptive Optics instrument for VLT's UT4, delivering corrected fields of view to a spectrograph, imager, and visiting instrument. Following Final Design Review, we present the Adaptive Optics Module (AOM) mechanical architecture. The optical bench supports post-focal relay optics (ADC, K-mirror derotator, deformable mirrors, selector) and rigidly mounts the calibration unit, guide star modules, and imager. The Overall Mechanical Structure connects to the Nasmyth platform while supporting the spectrograph and providing environmental isolation. We present final design solutions emphasizing the K-mirror system, material selection, and mechanical adhesive selections, with validation through thermoelastic, modal, and structural analyses.
