Stray light analysis of the Xinglong 2.16m telescope

27 Sep 2019 Li Taoran

An effort towards understanding of the stray light problems for the Xinglong 2.16-m telescope was presented to estimate the stray light performance of the telescope itself and provide a method for improving the stray light suppression. The stray light analysis for 2.16-m telescope model, which consists the onion shaped dome, telescope structure, equatorial mount and telescope optics, has been performed with two cases (1) point to 60{\deg} and (2) point to zenith, in both azimuth and elevation direction...
