摘　　要：分析了二级光谱的成因以及消二级光谱的条件。介绍了二元光学器件的阿贝数和相对色散与普通光学玻璃的差别。并将二元光学面刻画在透镜的表面,在校正系统初级像差的同时,实现了系统的复消色差。该系统结构简单、质量轻,可用于小型长焦距望远系统中。The theory of secondary spectrum which exists in long focal-wide bands optical systems is introduced in this paper and the qualifications needed to eliminate are also analyzed. BOL devices and ordinary optical glass have different Abbe number and relative aberration. By chiseling a BOL on a surface of a lens, a apochromatic system is composed,which actualizes the system＇s apochromatism,as well as revising primary aberration. Experimental results show that the system is characteristic of simple structure and light weight and can be used in mini-long focal telescope systems.
