摘要
通过分析焦度计的光源设计原理,我们发现了因光源波长导致色散出现致使镜片检测出现较大误差的问题,然后通过对色散原理的解读,提出了如何最大限度减少因色散产生误差的方法,最后利用相关测试方法论证了这一解决方案的合理性。
Through analyzed the design principle of lensometer＇ s photo source, we discovered the obvious error in the process of testing lens due to the dispersion caused by the wavelength of light resource. After that we interpreted the principle of dispersion and proposed the methods of reducing the error caused by the dispersion. Finally we demonstrated the rationality of solution by some relevant test ways.
