摘要	For a cool 320240 detector with staring focal plane array, an dual field of view infrared system for middle wavelength is designed. The system using positive electromechanical athermalization technology employs the axial motion of a lens group along the optical axis to change fields. The optical simulation and image evaluation are listed. The design results prove that the system had eight lens and worked at 3.7~4.8m has achieved the zoom of 50mm and 200mm, and satisfy 100% cold shield efficiency. The modulation transfer function is all above 0.5 at the Nyquist frequency when the temperature is between -50 and 60. The system is characterized by excellent images, simple structure and athermalization.
