    Aditya-L1 is the first Indian space mission to explore the Sun and solar atmosphere with seven multi-wavelength payloads, with Visible Emission Line Coronagraph (VELC) being the prime payload. It is an internally occulted ...
  • Experimental Validation of a Novel Concept to Reduce Optical Surface Wave Front Errors by Using Deformable Bushes at Opto-Mechanical Interfaces 
    Nagabhushana, S; Prasad, B. R; Nagesh, Suresh; Venkata Suresh, Narra; Sandeep, D. S; Kamath, P. U; Misra, Shalab; Hegde, Bhavana; Utkarsha, D; Sinha, Mrityunjay Kumar; Kathiravan, S; Natarajan, V; Pawan, Kumar; Amit Kumar (World Scientific Publishing, 2022-03)
    One of the major objectives of the optomechanics is to support large optics required for the purpose and also to maintain high dynamic stability in operation. This requirement calls for more number of supports, to support ...
  • Optical metrology on primary mirror of visible emission line coronagraph on board Aditya-L1 mission 
    Venkata Suresh, Narra; Singh, Darshika; Venkatasubramanian, N; Budhiraju, Vishweshwar Rao; Hegde, Bhavana; Bhat, Nishchith; Utkarsha, D; Somasundaram, P. K; Ramaswamy, Venkateswaran; Kamath, P. U; Sriram, Kuppuswamy Venkatesan; Prasad, B. R (SPIE-Society of Photo-Optical Instrumentation Engineers, 2022-10)
    The visible emission line coronagraph (VELC) on board the Aditya-L1 mission is an internally occulted reflective coronagraph. It is capable of simultaneous observations of the solar corona in imaging, spectroscopic, and ...
