合束镜
Beam-combination mirror
合束镜是一种半透反射镜，它将两种（或多种）波长的光线分别通过透射和反射的方法合成到一条光路上。
The green laser is a semi-reflection mirror. It combines the light beams of two (or more) wavelength into one direction by transmission and reflection.
由于采用硒化锌、硫化锌或锗材料并镀有优化设计的薄膜，合束镜通常透射红外光，反射可见光。
Since applying ZnSe, ZnS or Ge and coating with optimized layer, the beam-combination mirrors usually transmit infrared lights and reflect visible lights.
合束镜理想的应用在利用激光二极管做校准的系统中，
The ideal application of beam-combination mirror is to be used in the calibration system of laser diode.
合束镜设计用于45度入射时, 传输长波的激光束, 并利用90度反射的二激光光束来校准它。如下图：
When the angle of incidence is 45 degrees, the beam-combination mirror is designed to transmit long wavelength laser beams and the diode beams reflected at 90 degrees will be used to calibrate it. The design is indicated as followed:
