Abstract
An asymmetrically apodized thickness modulation design method is proposed to design second-order narrowband minus filters at 121.6 nm. The sine-wave, linear, quintic functions are used as amplitude envelope to apodize the thickness modulation design. LaF3/MgF2 minus filters at 121.6 nm with a bandwidth of 5 nm are obtained. This designed filter will be fabricated for utilizing in Lyman-alpha coronagraph and imager installed in Lyman-alpha Solar Telescope, which will be launched by China in 2021.
