manufactures several continuously variable attenuator models, known as Watt Pilot. Watt Pilot incorporates a high-performance polarizing cube beamsplitter or Brewster type thin-film polarizers which reflect s-polarized light while transmitting p-polarized light. A rotating quartz Phase λ/2 waveplate is placed in the incident polarized laser beam. The intensity ratio of those two beams may be continuously varied without alteration of other beam parameters by rotating the waveplate. Ratio can be controlled over a wide dynamic range. Pure p-polarization could be selected for maximum transmission, or pure s-polarization for maximum attenuation of the transmitted beam.
