  • Development of a temperature controller for the order-sorting interference filters 
    Banyal, R. K; Ravindra, B (Indian Institute of Astrophysics, 2012-08-01)
    A Fabry-Perot narrow band imager (NBI) is being built for solar studies at IIA [1]. The NBI has an order sorting pre- lter that selects an optical beam within desired wavelength band. A constant temperature is required ...
  • A Dual Fabry-Perot based imaging Spectrometer for the National Large Solar Telescope 
    Ravindra, B; Banyal, R. K (Indian Institute of Astrophysics, 2010)
    This report provides a detailed design of a dual Fabry-Perot based narrow band imaging system intended to make observations of solar atmosphere at visible and near infrared wavelengths. The narrow band imager will serve ...
  • Solar G-band observations at Merak, Leh/Ladakh 
    Vasantharaju, N; Dorjey, N; Ravindra, B; Prabhu, K; Rangarajan, K. E; Prabhu Ramkumar, B; Sankarasubramanian, K (Indian Institute of Astrophysics, 2012)
    G-band observations are important for the study of dynamics of magnetic features in the solar photosphere and they are carried out using large telescopes, larger than 30 cm. We installed a 40 cm DFM telescope at one of ...
