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.
