Diffractive Multifocal lenses (MF) are widely used for glass cutting applications. Holo/Or has develop a tailored focusing module for glass cutting applications, integrating MF with a focusing objective. Unlike refractive solutions, Holo/Or’s diffractive MF focus module works for single as well as multi mode lasers, and maintains diffraction limited spots size at all foci.
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
