分束光柵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.
分束光柵用于將激光光束分成一維或者二維的分束光柵(光束分束),分束光柵每束光除了功率和傳播角度與原有光束不同外,分束光柵其余光學(xué)特性都與原光束保持不變。
