介质镜 meaning in English

dielectric mirror

The blocking - layer and the dielectric mirror separate the write beam and the read beam , and the dielectric mirror reflects the read light also . in order to separating the write beam and the read beam quietly , and reflecting the read bean in the most limit
液晶光阀的阻光层和介质镜层起着隔离写入光和读出光的作用，介质镜层还起着反射读出光的作用。
The optimal combination of the blocking layer and dielectric mirror is ascertained by the research of the optical performance of the blocking layer and the dielectric mirror . it is that the thickness of the blocking layer is more than 1 . 3um and the layer - number of the dielectric is 9 . the combination of the multiplayer - film is the primary problem which presence at the fabrication of lclv
本文通过对阻光层和介质镜反射层的光学特性研究，用实验的方法确定了反射率最大而透过率最小的阻光层和介质镜反射层最佳组合为：阻光层厚度在1 . 3 m以上，介质镜层数为9层。
