Knife-edge beam profiler; 3 mm circular with 3 knife edges; profiles beams down to 3 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-USB BM-3 InGaAs is a high-precision multiple knife-edge scanning laser beam profiler that can measure focused spots as small as 3 microns from 800 to 1800 nm. This model incorporates a 3 mm diameter InGaAs detector.
The BM-3 model uses three individual knife-edges on a rotating drum to scan the beam through three different axes in a single rotation. The beam shape and dimensions are calculated by combining data from the three scans to reconstruct a profile of the beam.
