Design of the Wide Bands Fourier Lens
干涉成像光谱仪中宽谱段傅氏光学系统设计

A kind of wide wave band, collimated optical system was designed, which the aperture locates in the front focus. In this design, auto-corrected chromatic aberration, long work distance, front aperture and collimated rays were concentrated in one. In this thesis, all these were discussed. Glasses partner were selected in Chinese, it is very cheap, and after correct the chromatic, the secondary spectrum of this wide wave band optical system also were corrected. In the same time, the system realized the long work distance both in its front and back side. The result show that the residual secondary spectrum of the system is less than one thousandth focal length, and the parallel error of rays of the wavefront less than 0.000 22 rad.
