A new, lightweight, compact processing head from the Coherent division formerly known as LASAG is optimized for industrial laser applications where space is limited and minimum mass is required. Specifically, the new FLBK40 is a modular beam delivery system, including a variety of collimators, focusing lenses, cameras, camera adapters and an IR illuminator, that can be rapidly configured by the user as needed to deliver optimum performance for a wide range of fiber laser-based cutting, welding or drilling applications.
