干涉成像光谱仪中宽谱段傅氏光学系统设计

Design of the Wide Bands Fourier Lens

设计了一种宽谱段前置光孔远心光学系统,其孔径光阑位于透镜组的焦面上,该设计集宽谱段自动复消色差、长工作距、前置光孔及远心等特点于一体.讨论了这样一种特殊光组的设计.选用国产牌号的光学玻璃配对,价格低廉且在校正色差后,自动校正宽谱段二级光谱,并实现了透镜组两侧同时具有长工作距.设计结果表明,光学系统的残余二级光谱很容易控制在千分之一焦距以内,波面平行差小于0.00022弧度.

A kind the front focus. and collimated rays selected in Chinese wave band optical s both in its front an than one thousandt de wave band, collimated optical system was designed, which the aperture locates in is design, auto-corrected chromatic aberration, long work distance, front aperture were concentrated in one. In this thesis, all these were discussed. Glasses pfirtner were , it is very cheap, and after correct the chromatic, the secondary spectrum of this wide ystem also were corrected. In the same time, the system realized the long work distance d back side. The result show that the residual secondary spectrum of the system is less h focal length, and the parallel error of rays of the wavefront less than 0. 000 22 rad.
