Division I facet stones processing more than 60 workers, required to have the ability to produce all types of gemstones qualified products, main processing gems as: natural gemstone categories: olivine, garnet and white topaz, apatite crystal. Artificial gem categories: Glass and Mirror, Robert zircon, synthetic corundum, synthetic crystal, and other sharp.
我司有娴熟的宝石加工工人六十余名，有能力按要求生产出合格的各种类型宝石产品，主要加工宝石为：天然宝石类：橄榄石、石榴石、白黄玉、磷灰石、水晶等，人工宝石类：玻璃及镜面、立锆、合成刚玉、合成尖晶等。
External cavity feedback for a broad-area laser diode with antireflection coating on the front facet was investigated experimentally. The feedback was created by a high-reflection mirror and a blazed grating, which reflected two parts of the laser emission back to the BAL, thereby forming an external resonator.
实验研究了宽接触条形双外腔反馈半导体激光器，在该激光器的输出表面镀增透膜，反馈是由高反射率平面镜和闪耀光栅组成，通过调整平面镜和光栅的倾斜角度，使得特定的空间模式和纵模注入半导体激光器，使之产生振荡，并抑制了激光腔内振荡的其他横模和纵模数，从而输出单瓣近衍射极限的激光束。
The application of the two-facet mirror makes it possible to use much less moveable mirrors than the cross-bar configuration, and simplifies the control program with improved reliability of the optical switch matrix.
在基于双面反射镜的光开关矩阵中，双面反射镜的使用大大减少了光开关矩阵中运动镜片的数量，简化了控制程序，并有利于提升光开关器件的可靠性能，有望在中小型光交换机、网络管理和光路测量中获得应用。
At last, the important details are given in designing the scanning mirror, care shall be given to the deformation of the facet and efforts shall be made to avoid the jitter from driving torquer, which will interfere the natural modal.
为了减少驱动电机的尺寸和功率，扫描镜一般都设计得较薄，因而刚性较差，在惯性力的作用下面形容易发生变化且易发生共振[1]。所以，在设计扫描镜
The polygon-mirror laser scanning system for PAL standard TV was discussed. The relationships between the polygon facet number and its rotating speed, the reflection facet length were presented.
讨论了适用于PAL电视制式的转镜-振镜结构激光扫描系统，计算了转镜的面数和转速、反射面长度间的关系。
