A reimaging F/1.0 long-wavelength infrared optical system is proposed. The design has a flexible opto-mechanical layout. The design process is as follows. Firstly  the catadioptric reimaging system consists of two reflecting mirrors and a relay lenses. Two reflecting mirrors make up of the first imaging system and are therefore free of chromatic aberrations  while low dispersion lenses were used in the reimaging system  so the optical system do not need achromatic design for a high image quality. Then  to correct high-order aberrations resulting from large relative aperture  more parameters need to be used with aspheric or diffractive surfaces due to modern optic technology development. Here  aspheric is selected for easily manufacture. Finally  the design is completed with the help of ZEMAX software. The effective focal length of the objective is 120mm and the field of view (FOV) is 4. The simulated final design shows adequate image quality and the modulation transfer function (MTF) is close to diffraction limit. The effect of the surrounding environmental temperature is analyzed using the concept of thermal defocusing  and the thermal compensation is discussed. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

In order to get enough information about the target  avoid big chromatic aberration as a result of wide spectrum and the complexity of optical system and adapt different special environment temperature  a hybrid refractive/harmonic diffractive optical system in far-infrared multi-band is described in the paper. This diffractive optical system has been designed an athermalized multi-band imaging system with harmonic diffractive element in 15-50m spectrum  based on larger 1dispersion capability and particular thermal dispersive power of harmonic diffractive element. Then  at the temperature range from 0C to 40C  this design can simultaneously meet with all requirements of the imaging system in five harmonic wave bands  including15.8-16.2m  18.5-20m  23-25m  30.5-33.5m and 46-50m. In each harmonic wave band  the magnification changes as a function of wavelength  which creates image registration error. To compensate this shortcoming  a zoom optical system is designed with three lenses by means of optical two- component method. The design results show that the hybrid refractive/harmonic diffractive optical system can realize athermalized and achromatic design  and the zoom optical system makes half image height at 3.53mm in every harmonic wave band and still realizes aberration compensation action. In the five harmonic wave bands  each optical transfer function approaches the diffraction limit at ambient temperature range of 0C to 40C. Finally  the system realizes the requirements of portability  mini-type and ease for fabrication. 2009 SPIE.
