Continuously Variable Attenuator / Beamsplitter 990-0060 Series for Broadband Region

  • Divides laser beam into two beams of manually adjustable intensity ratio
  • Convenient 90° angle between reflected and transmitted beams
  • Negligible beam deviation
  • Large dynamic range
  • Broadband transmission
  • Weight – 0.16 kg

Continuously Variable Attenuator/Beamsplitter is designed for down to 100 fs laser pulses. It consists of 2 high-performance polarizing optics components placed in precision opto-mechanical holder 840- 0197. Variable attenuator/beamsplitter incorporates a high-performance Polarizing Cube Beamsplitter which reflects s-polarized light at 90° while transmitting p-polarized light.

A rotating 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. The intensity of either exit beam, and their intensity 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.
