摘要
一般的光学系统在两个消色差波长B和C的像点校正重合后,与参考波长A的像点仍有一定的偏离,称为二级光谱,它与系统的焦距成正比。在焦距一定的情况下,由于二级光谱是由两块玻璃的相对色散差与阿贝常数差的比值来确定的,因此只有相对色散小,阿贝常数又足够大的玻璃组合,才能较好地校正二级光谱。因而长焦距复消色平行光管物镜是光学设计的两大难题之一,本文采用等效玻璃的方法,再根据复光焦度、位置色差、二级光谱的约束条件,导出了求解三胶合复消色差平行光管物镜初始结构方程式,求解出满足复消色的光焦度解。

ABSTRACT
General optical system achromatic wavelength in two B and Cas the point after the correction of coincidence with the reference wavelength A as there is still a certain degree of deviation from the point known as the secondary spectrum, which is proportional to the focal length of the system. In the case of a certain focal length, as the secondary spectrum is the relative dispersion between two glass poor and the Abbe constant ratio to determine, therefore, only relatively small dispersion, Abbe constant of the glass and is large enough portfolio to better to correct the secondary spectrum. So long focal length of plex achromatic collimator lens optical design is one of the two major problems,In this paper, the equivalent glass method, and then Fuguang focal power in accordance with, the location of chromatic aberration secondary spectrum constraints is derived for solving the three bonding Apochromatic lens collimator structure of the initial equation to solve to meet plex achromatic solution of the optical power.

平行光管简介
根据几何光学原理,无限远处的物体经过透镜后将成像在焦平面上;反之,从透镜焦平面上发出的光线经透镜后将成为一束平行光。如果将一个物体放在透镜的焦平面上,那么它将成像在无限远处。
常用平行光管一般都物镜、分划板和玻璃组成,。分划板置于物镜焦
