optical surface

By applying The Law of Conservation of Energy and the theory of complex beam parameters of laser beams, the complex matrix element of optical surface of shaping optical system can be obtained.

运用能量守恒，以及光束复参数理论，获得描述用于整形的光学系统的光学复数矩阵元。

This paper presents some technological barriers in producing the new secondary mirror for Φ 2.16m telescope and introduces the methods which have been adopted to resolve these technical problems. The possibility that optical surface is produced smoothly by selecting suitable shape of tool is discussed.

介绍了Φ2.16m望远镜新副镜加工中的一些工艺难点及所采取的方法，定性分析了选择合适的工具形状，使镜面面形平滑过渡的可能性。

Scrub each optical surface with a gauze pad soaked in acetone. Rinse thoroughly with distilled water.

或者用含丙酮的网垫擦洗光学表面. 然后用蒸馏水漂洗.
