Features


  • Measurement of F/5 beams with λ/100 accuracy, including astigmatism and high-order aberrations

  • Patented technology for simultaneous and independent phase and intensity measurements

  • External trigger feature ensures accurate measurement time

  • Low latency of 2.2ms for high performance adaptive optics

  • Only 1 nW power required on sensor at 1kHz

Applications


  • Quantify the optical system’s aberrations

  • Align the system to ensure that it performs at its best

  • Drive a deformable mirror to do high frame rate adaptive optics

  • Quantify the transitional regime of active optical elements such as variable focal length lenses

  • Verify that the optics comply with specifications

  • Directly measure the optical system’s wavelength dependency

  • Quantify the pointing stability of high frame rate laser

  • Check whether the optical mount overly distorts the optics
