The 3,6 m Indo-Belgian Devasthal Optical Telescope: assembly, integration and tests at AMOS

摘要

AMOS SA has been awarded of the contract for the design, manufacturing, assembly, tests and on site installation(Devasthal, Nainital in central Himalayan region) of the 3.6 m Indo-Belgian Devasthal Optical Telescope (IDOT).The telescope has a Ritchey-Chrétien optical configuration with a Cassegrain focus equipped with one axial port and twoside ports. The meniscus primary mirror is active and is supported by pneumatic actuators. The mount is an Alt-Az typewith for the azimuth axis a 5 m diameter hydrostatic track.The telescope was completely assembled and tested in AMOS workshop. This step is completed and successful. Thetelescope is now ready for shipment to Nainital.This paper describes the test campaign at sub-system and system level that has taken place to demonstrate that thetelescope satisfies the main system requirements. Besides of the functionality of the telescope, the units interacting withthe image quality or the tracking performance were plenty tested. Some selected tests directly connected to theperformance of the telescope are also looked specifically in this paper.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
