Knife-edge beam profiler; 5 mm circular aperture with 3 knife edges; profiles beams down to 15 µm, InGaAs detector with 800 to 1800 nm spectral range.
Laser Beam Diagnostics system includes a knife-edge profiler, USB interface module, and beam diagnostics software.
BeamMaster BM-7 InGaAs 5mm is a high-precision multiple knife-edge scanning laser beam profiler that can measure focused spots as small as 15 microns from 800 to 1800 nm. This model incorporates a 5 mm diameter InGaAs detector.
The BM-7 model 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 data from seven scans to reconstruct a profile of the beam.
