一种新的长焦距透镜的制造方法

A New Manufacture Technique for Long Distance Focal Length Lens

论述了用平行平板上盘来加工长焦距透镜的方法，这种方法可避免火漆上盘引入的透镜偏心。实验证明这种加工方法重复精度好，生产效率高，适合批量生产。

This paper describes a new technique method to produce long distance focal length lens with optical paralel to make a block. It can avoid the eccentricity of lens caused by blocking with sealing wax. The experiments verify that this method has good repeability, high productivity. It is applicable for batch production.
