Paper Abstract

A 3mm narrow interval deformable mirror (DM) with tip-tilt stage has been developed for astronomical instruments. Benefiting from its compact design, the adaptive optics system can be built with simple structure and smaller optical elements. First, a 37-elements prototype mirror has been developed for our 1.8-meter telescope, which interval space is 3mm, maximum tilt is ±10’, and maximum deformation is ±2μm. Based on this mirror, a simple adaptive optics system has been set up and its performance was tested in the laboratory especially the closed-loop correction ability. This adaptive optics subsystem is scheduled to be mounted at one folded Cassegrain focus of the 1.8-meter telescope this year, and comparison test for star compensation observation using this compact system and conventional adaptive optics system will also be carried out at the same time.
