Laser Beam Profiler, CW, 5mm Aperture with 7 Knife-edge, InGaAs Detector
Numéro de référence fabricant :
BeamMaster-USB BM-7 InGaAs is a high-precision 5mm circular with 7 knife edges InGaAs detector scanning laser beam profiler, which can be configured to sample, measure and display cross-sectional profiles and/or 2D and 3D image plots in real time up to 5 Hz. Selectable averaging of 1-20 samples provides noise reduction and maximizes measurement accuracy.
The BeamMaster model BM-7 uses seven individual knife-edges on a rotating drum to scan the beam through seven different axes in a single rotation. This provides more accurate measurements of the true beam shape and dimensions by tomographically combining the data from all seven scans to reconstruct a profile of the beam. This technique also makes locating the angular orientation of elliptical beam major/minor axes much easier than searching by rotating the sensor head around the optical beam axis.
