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.
This series of sampling lenses can extract a small portion of the laser beam for power monitoring or other purposes. The method used is diffraction, extracting the+-1st order diffraction beam as the monitoring and the 0th order diffraction beam as the main beam, entering the main working optical path.
