Beam Profiler

The BPF series have unique fluorescence imaging technology. The beam profile of high power lasers can be directly measured without any attenuators in front of the imaging plate.
You can realize true behavior of your laser beam from the precise, real-time, real-place, speckle-free images of the BPF series.

Measurement (software)
  • 2D/3D View (intensity profile)
  • 1D Cross sectional view
    X/Y-cut, Radial-cut, Arbitrary-cut, etc.
  • Beam diameter calculations
    Threshold, D4σ, Gauss/Super-gauss-fit, Knife-edge, Moving slit, etc.
  • 2D Beam parameter calculations
    Centroid, Azimuth angle, Ellipticity, Eccentricity, Uniformity, Cross-sectional area, etc.
  • Beam propagation parameter calculations
    Divergence angle, Beam waist diameter, Rayleigh length, M2 value, etc.
  • Beam stability
    Centroid, Beam diameter, Peak intensity, Power, etc.

  • Caution : Some measurements need higher software version (upgrade).
