Binary optics element(BOE)used in conventioi1al system can provide addition alparamemeters

freedom for material selection in optical design.This thesis mainly studies theimage properties & the methods of design and fabrication :By using two equivalent models

BOE’s primary aberrations are deduced

the reason for the difference of these two models is analyzed;lst order and 3rd order image properties and chromatic aberrations are presented

and the program for the aberration analysis and the prelimenary solutions of refractive-diffractive hybrid system.which satisfies the balance of primary aberrations is accomplished

the resuIts are comsistent with those given by CODE-V;The algorithm and program formask generating are presented

and the mask film is output using laser imager.With the design examples for some typical systems in visible

ultra-violet

infrared band

the applicationsof the BOE and its limitations are discussed in the end.
