摘要
本文所述的光学系统被用于星模拟器上。本设计成功的关键在于对双胶、双分透镜组来说，打破了常规地选用火石玻璃－火石玻璃（Ｆ－Ｆ）的组合；在系统总焦距不变及二级光谱维持最小值的前提下，最大限度的降低了每块透镜的光焦度；再辅以前后组在正光路和逆光路中各色光的像面位置及像差的精细配合，使在第一阶段唯一没有满足要求的畸变由１９″降低到２．３１８″，达到了所要求的指标。
Optical system argued in the paper is applied on the apparatus of artificial star. The successful key consists in the double adhesive and double separate lens which select flint flint (F F) the combination; on the condition of total focus being unchanged and keeping the least secondary spectrum, optical dioptrie of every piece of len is decreased to the largest extent; besides the array orders of spherical aberration curve of each colorama are unitary and their total width is about equal, in positive and opposite optical path of front and rear group. So distortion is decreased from 19″ to 2 318″.
