Laser metal deposition (LMD) and 3D metal printing using high-power fibre lasers place extreme strain on the eyes. In addition to the need to block infrared radiation with power in the kilowatt range, it is essential to protect the eyes from omnidirectional reflections and the dazzling brightness of the molten pool. These models therefore offer the highest available protection levels (LB) to ensure maximum safety even in demanding operating conditions.
