With the development of optical information processing  high-resolution Fourier transform lens has often been used in holographic data storage system  spatial filtering and observation of particles. This paper studies the optical design method of high-resolution Fourier transform optical lenses system  which could be used in particles observation and holographic data storage system. According to Fourier transform relation between object and its frequency plane and the theory of geometrical optics  the system with working wavelength 532nm and resolution 3 m was designed based on ZEMAX. A multi-configuration method was adopted to optimize the system's lenses. In the optical system  a diaphragm was placed at the system's spectrum plane and the system demanded a low vacuum to cut down the influences of atmosphere and other particles. The result of finite element analysis indicated that the influences of vacuum pumping to optics spacing and mirror surface shape very minor  and the imaging quality not being affected. This system has many advantages  such as simple structure  good image quality and a high resolution of 3 m. So it has a wide application prospect and can be used both in holographic data storage system and particles observation.
