Focus Measurement

All DataRay's ISO 11146-compliant beam profilers, including Beam Profiling Cameras and Scanning Slit Beam Profilers, can measure a beam focus. Our cameras can directly measure focus spots as small as 32 um in diameter. Our scanning slit beam profilers can directly measure focus spots as small as 2 um in diameter. We also design affordable reimaging and magnification systems to profile inaccessible beam waists, or beam waists outside the limits of a direct measurement.

Direct Measurement
  • Camera-based
    • For focus spots 32 um or larger in the 190-1350 nm wavelength range
    • Provides accurate diameter measurement, 2D image and profiles
    • Option to measure spots 170 um or larger in the 2-16 um wavelength range
  • Scanning slit-based
    • For focus spots 2 um or larger in the 190-2500 nm wavelength range
    • Provides accurate diameter measurement and summed X/Y profiles
Measurement with Reimaging or Magnification
      • LensPlate2
        • For inaccessible beam waists or beam waists outside typical diameter limits
        • Calibrated by DataRay to provide accurate magnification factor

    • LensPlate2-PPBS
      • For high power focus measurements that require reimaging or magnification
      • Reimaging system with integrated high-power beam sampler
      • Calibrated by DataRay to provide accurate magnification factor
