相比透射型组合滤波器件，提出了只需要由一种反射元件构成的反射型组合滤波器件的光路。在保证角谱选择性的前提下，降低了设计和制备的难度。另外，通过膜系设计和电场强度比较，发现此反射型组合器件具有比透射型组合器件更高的抗激光损伤阈值(LIDT)。因此，为反射型介质膜组合滤波器件的制备和应用奠下了基础，具有重要的指导意义。

Comparing with transmission combination filtering device, only one type of reflection element is presented in optical path of reflecting combination filtering device. The difficulty of design and preparation is largely decreased in the same angular spectrum selectivity. In addition, by comparing the design of coating stacks and the electric field strength, reflecting combination device has higher laser- induced damage threshold (LIDT) than the transmission. Thus, the device plays an important role in preparation and application of the dielectric multilayer film reflecting combination device.
