2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.
