Abstract

In this paper, we propose a new type of optical baffle with radial leaves, which can effectively reject stray light caused by primary mirror scatter while makes the baffle length shorter than the ordinary one. The stray light test setup for measuring the Point Source Transmittance (PST) of such an optical baffle is described. The test results show that this type of optical baffle can well suppress the stray light from an out-of field light source.
