Diffractive beam samplers are used to monitor highpower lasers by extraction of exact sampled copies of the beam with only a small fraction of the total power. The passing beam corresponds to the zero diffraction order, while two sampled beams propagate at the symmetrical angles of the first diffraction orders. We offer our high quality beam samplers for various angles and power fractions of sampled beams.
此系列的取样透镜可从激光束中提取一小部分光束，用作功率监测或是其他用途。采用的方法为衍射方法，提取+-1阶衍射光束作为监测，0阶衍射光束作为主要光束，进入主要工作光路。
