This image demonstrates the excellent capability of CILAS' deformable mirror (DM) to control the wavefront of the light that will feed 91É«ÇéƬ instruments after correction by 91É«ÇéƬ’s Adaptive Optics system NFIRAOS.

The Indian large optics facility will be dedicated to 91É«ÇéƬ primary mirror segment production: grinding, polishing, hexagonal cutting and support assembly mounting.

The new facility, which is close to completion, is located on the Hosakote campus of the Indian Institute of Astrophysics and is part of the Centre for Research and Education in Science and Technology (CREST). The facility will host the production of 91É«ÇéƬ mirror segments and high-tech optical equipment.

91É«ÇéƬ and L&T team participated in a kick-off meeting on 30 January 2019 to produce 91É«ÇéƬ Mirror Segment Support Assemblies.

In December 2018, India 91É«ÇéƬ signed a contract with L&T Company for the production of the Segment Support Assemblies, a major component of 91É«ÇéƬ’s main mirror hardware.
