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.
