Simulation of Residual Optical Aberrations of Objective Lens 210/3452 of Solar Spectrograph of Ondřejov Observatory
Rail, Zdeněk ; Jareš, Daniel ; Melich, Radek
At the end of 2012 was done measuring and clean the lens 210/3452 of the solar spectrograph Observatory Astronomical Institute Academy of Sciences in Ondrejov. The spectrograph is working in line H-alpha and is formed by a birefringent lens-polarizing filter, positioned in front of the focal plane. The measured values are enumerated in the optical properties. In a report to present to the results of mathematical quantification of residual defects and new optical system design suitable for use Fabry-Perot filters.
