Laser beam alignment can be tricky. With the newly launched gRAY Laser Beam Position Detectors from greenTEG power measurements and position detection can be conducted at the same time. The laser beam position detectors are sensitive to all wavelengths from UV to MIR. Powers from tens of μW to W can be detected independent of the beam angle. The compact design of the detector modules make system integration easy.
Matthew Dale explores some of the latest technology for manipulating and measuring the beam, including a multi-spot optical module for laser brazing and a contactless beam analysis device
Moving to very high power lasers for welding metals, like aluminium in car production, has some big benefits, as Greg Blackman finds out
