Beam Profiler

BPF-L400/L800/L900 is the fidelity beam profiler with unique transfer imaging technology. The beam profile of high power lasers can be directly measured without any attenuators in front of the imaging plate.
You can realize true behavior of your laser beam from the precise, real-time, real-place, speckle-free images of BPF-L400/L800/L900.
