IdealPhotonics' knife-edge beam analyzer is a high-precision measuring instrument that reconstructs the two-dimensional contour of a beam by scanning the beam cross-section line by line through a high-speed moving physical slit, simultaneously recording the transmitted light intensity distribution. It is particularly suitable for saturation-free detection of high-power lasers.Mechanical point-by-point scanning resists light saturation, enabling accurate beam reconstruction of high-power lasers.
