Talha (Depart ent of Optoelectronic Engineering, Beijing Institute of Technology , Beijing 100081, China) Abstract A metho base on the 3r -or er aberration theory is escribe for the esign of mechanically compensate reflective zoom systems with 3 mirrors. By constraine optimization of a set of Sei el aberration coefficient functions, the initial construction parameters of the optical system can be achieve , an the esign results prove the feasibility of this metho . The limitation of the above metho an the necessity of the esign of reflective systems without obscuration are also pointe out. A new esign theory is explore which coul eliminate obscuration an correct aberrations at the same time. Key words optical esign; mechanical compensation; zoom system with 3 mirrors; Sei el aberration theory; construction parameters; without obscuration 1 1980 , [ 1] , , [2~ 4] 2 , , , [5,6] () , ( , ) , [ 10, 11] : [7, 8] L 1 = 1 - B21 f c2+ 1 - B31 f c3, ( 1) B21 B31 L i = 1 - B2i f c2+ 1 - B3i f c3, i = 2, ,, k
