光柵分束器Diffractive beam-multiplication elements split a laser beam into several beams, each with the characteristics of the original beam except for power and angle of propagation. Focusing multi-spot elements provide a line or an array of identical focal spots located in the focal plane, with spacing between neighboring spots.
光柵分束器用于將激光光束分成一維或者二維的光柵分束器(光束分束鏡),光柵分束器每束光除了功率和傳播角度與原有光束不同外,其余光學特性都與原光束保持不變。
