本文评述光学复制工艺及其优缺点.在复制件的设计和稳定性以及制作时材料的选择方面,在受热应力和动态应力状态下,基底尺寸稳定性都是很重要的.本文的分析帮助人们去选择材料,对于用来制作有低动态偏差的表面结构来说尤为重要,并叙述了一些材料有尺寸不稳定的典型现象,给出了材料和工艺方法的有关数据.解决尺寸不稳定性问题方面特别成功. This article reviews the optical replication process and its advantages and disadvantages.The dimensional stability of the substrate is important both in thermal stress and dynamic stress conditions in the design and stability of the replica and in the material selection during fabrication.The analysis in this article helps people Deselection of materials is particularly important for the fabrication of surface structures with low dynamic deviations and describes some of the typical phenomena of material size instability and gives data on materials and process methods Solving dimensional instability problems Particularly successful.
