英文摘要	To achieve precise applications under specific environmental requirements, an infrared optical system that can be applied to near-infrared wavelengths was designed. First of all,based on the selected parameters 1/4-The initial structure was selected and the form of the Maxutov telescope was selected and improved.Then 1/4-The detection performance of the design results was analyzed.Due to the large range of high and low temperature changes in the outer space environment, the system lens barrel material analysis was carried out to obtain the influence of temperature changes on the energy distribution of the optical system.Finally 1/4-A tolerance analysis and optimization of the designed system were conducted so that it could meet the needs of processing and assembly.The design and analysis results indicate that the optical system adopts a spherical catadioptric mirror surface, the total length of the system is 126.218mm, the full field of view for a 14 μm surrounding energy distribution is > 80%, the maximum magnification chromatic aberration value of monochromatic light with a center wavelength of 1.3μm is © COPYRIGHT SPIE.
