Abstract

AMOS SA has been awarded of the contract for the design, manufacturing, assembly, tests and on-site installation (Nainital, Devasthal site at 2540 mm altitude) of the 3,6 m Indo-Belgian Devasthal Optical Telescope (IDOT). The primary mirror is a meniscus active mirror. This paper describes the opto-mechanical design of the M1 unit and provides some test results performed on sky to demonstrate the proper functioning of the active system.
