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.

此系列的取樣透鏡可從激光束中提取一小部分光束，用作功率監測或是其他用途。采用的方法為衍射方法，提取+-1階衍射光束作為監測，0階衍射光束作為主要光束，進入主要工作光路。
