| 摘 要： | 介绍一种相对孔径为1:1的光谱摄像镜头。利用非球面光学表面将复杂化的Petzval型结构形式改进为3片结构,其主要光学参数f′=120mm，F=1，τ≥90%，系统MTF=0.85时的成像质量所对应的空间频率大于20lp/mm。结合非球面加工工程化研究需要对该镜头的结构进行优化，给出了多种像差曲线及MTF数据，并对未来可进行的进一步改进进行了探讨。 |

| Abstract: | A spectral camera lens with the relative aperture of 1 : 1 is introduced. The complicated Petzval structure is converted into a triplet structure based on aspheric surface. The primary optical properties are: f'=120 mm,F = 1,τ≥ 90%. The spatial frequency is greater than 20 lp/mm when the MTF value of the optical system is equal to 0.85. The lens structure is optimized to facilitate the machining of the aspheric surface. Several kinds of aberration curves and the MTF data are given,and the further possible improvement for the optical system is explored. |
| Keywords: | optical design lens with large aperture aspheric surface |
