    Saxena, A. K; Jayarajan, A. P; Kumar, K (Indian Institute of Astrophysics, Bangalore, 1980)
    The design and features of 1.5m vacuum coating plant an in house facility at the Kavalur Observatory for periodic aluminizing of astronomical optics are described. A typical performance data is given.
  • An analysis of Babinet compensator fringes using Jones calculus 
    Pandya, T. P; Saxena, A. K (Indian Institute of Astrophysics, 1978)
    Following Jones Calculus, a comprehensive theory of the Babinet Compensator has been presented. The performance of the system governed by the compensator-Polaroid unit, has been evaluated in terms of fringe visibility. ...
