摘要
在可见光波长λ=0 .5 1 45μm(氩离子激光 )上 ,测试了一口径为 1 80 mm的Ritchey- Chretien(R- C)光学系统在不同入射角 θ时的 PST(θ)。通过对比测试 ,证实了锥状遮光罩对 R- C光学系统视场外杂光抑制有良好效果。
At the visible wavelengthλ=0 .5 1 45μm (Argon ion laser) ,PST(θ) of a Ritchey- Chretien optical system with the entrance pupil diameter of1 80 mm for various incident angles of off- axis stray light source was tested.After comparison test,the cone baffle benefiting for suppressing of stray light out of field source in an R- C optical system was verified.
