The Standard version of the attenuator incorporates a rotating quartz λ/2 phase waveplate and High Energy Polarizing Beamsplitter cube that separates s-polarized and p-polarized beams in orthogonal directions. The whole optomechanical assembly is tightly packed to serve as a compact solution. Pure p-polarization should be selected for maximum transmission and pure s-polarization for maximum attenuation. The intensity ratio of separated beams is continuously tuned by rotating the waveplate.

A detachable beam dump is complementary with the product. Custom wavelengths are available upon request.

Contact us and we will find a solution for your beam attenuation, power control, beam splitting needs. We can also recommend compatible optical components for your beam-delivery applications.

Features

  • Compact design for manual operation
  • Available in high power and medium power versions
  • Convenient 90° angle between reflected s-pol and transmitted p-pol beams
  • Negligible beam deviation
  • Interchangeable optics
