K; Manoharan, P. K; Uddin, W; Sriram, S; Amit Kumar; Srivastava, N; Koteswara Rao; Nagendra, C. L; Chakraborty, P; Sriram, K. V; Venkateswaran, R; Krishnamurthy, T; Sreekumar, P; Sarma, K. S; Murthy, R; Navalgund, K. H; Samudraiah, D. R. M; Narayan Babu, P; Patra, A (Indian Academy of Sciences, 2011-01-25)
    The outer atmosphere of the sun – called the corona – has been observed during total solar eclipse for short periods (typically < 6 min), from as early as the eighteenth century. In the recent past, space-based instruments ...
  • Prospect for UV observations from the moon. III. assembly and ground calibration of lunar ultraviolet cosmic imager (LUCI) 
    Mathew, J; Nair, B. G; Safonova, M; Sriram, S; Prakash, A; Mayuresh, Sarpotdar; Ambily, S; Nirmal, K; Sreejith, A. G; Murthy, J; Kamath, P. U; Kathiravan, S; Prasad, B. R; Brosch, Noah; Kappelmann, Norbert; Gadde, Nirmal Suraj; Narayan, Rahul (Springer, 2019-03)
    The Lunar Ultraviolet Cosmic Imager (LUCI) is a near-ultraviolet (NUV) telescope with all-spherical mirrors, designed and built to fly as a scientific payload on a lunar mission with Team Indus—the original Indian entry to ...
  • Scatter due to Ultraviolet (UV) photopolymerization of molecular contamination on optical surfaces 
    Venkata Suresh, Narra; Prasad, B. R; Somasundaram, P. K; Kathiravan, S; Venkatasubramanian, N; Padavu, U. K; Mani, V. T; Basavaraja, S; Naik, Rajesh (Springer Nature B.V., 2020-12)
    Molecular contamination on optical surfaces is a serious issue for space payloads. For ultraviolet (UV) payloads, molecular contamination results in loss of throughput. Whereas, for visible (VIS) payloads loss of throughput ...
  • Visible emission line coronagraph on Aditya-L1 
    Prasad, B. R; Banerjee, D; Singh, J; Nagabhushana, S; Amit Kumar; Kamath, P. U; Kathiravan, S; Venkata Suresh, Narra; Rajkumar, N; Natarajan, V; Juneja, Madhur; Somu, Pawan; Pant, V; Shaji, Nigar; Sankarsubramanian, K; Patra, Asit; Venkateswaran, R; Adoni, A. A; Narendra, S; Haridas, T. R; Mathew, S. K; Mohan Krishna, R; Amareswar, K; Jaiswa, Bhavesh (Indian Academy of Science, 2017-08-25)
    Solar coronagraph mimics total solar eclipse by blocking the solar disk and enabling the observation of extended coronal atmosphere of the Sun. Visible Emission Line Coronagraph (VELC), on-board Aditya-L1 space mission, ...
