摘要
分析了常规透射镜组检测方法的缺点,在添加简单的辅助元件情况下,提出了一种新的检测透射镜组装调完成后整体组件的方法,从而解决了大口径光学系统应用中透射镜组的光学质量检测问题.分别以两个实际光学系统为例,给出了透射镜组的设计和准确度要求.随后利用该方法对实际系统中装调完成后的透射镜组进行检测,并将分析结果和实际检测结果进行比较,得出该方法的检测准确度优于0.01λ,证明了该检测方法的可靠性和正确性.最后用检测结果指导装调,使得透射镜组的最终装调完成后的质量满足了要求.
Abstract
As a frequent part of optical systems, the lens group plays an important role in the large aperture optical system, but the lens group can not be tested directly after alignment. The disadvantage during common measurement of the lens group was analyzed. With adding one simple optical element, a new method for testing the whole lens group after alignment, which solves the test problem of lens group applied in the large aperture optic systems. Two practical optical systems were given, and the design and accuracy demand of the lens group were analyzed. Next, the lens group of the practical optical systems with the new method were tested, and the comparison of analyzed results and test results proved the reliability and precision of this method, which derives that the precision of measurement is better than 0.01λ. At last, the optical quality of lens group after final alignment meets the design requirement.
