Optical system design of Full-Disc Magnetic Field Telescope
Full-Disc magnetic field telescope is an important instrument for astronomical observations.In order to meet the optical performance of the full-Disc magnetic field Telescope and the harsh coupling conditions of its filters, determined the optical parameters of the optical system by calculation. According to the calculation of the optical parameters, we puts forward a feasible optical structure which can make the system more compact under the premise of meeting the telescope in optical properties and filters coupling conditions. For the system, we have adopted the basic idea of modular design, and the overall system is divided into several subsystems were designed. The results show that the maximum wave front distortion(pv) of the system of all field of view is 0.1327/;the value of MTF at the spatial frequency of 67 lp/mm is higher than 0.45 in every field. The image quality of the system approximates to the diffractive limit
