Non-Contact Laser Beam Monitoring System

At Formnext MKS presents Ophir BeamWatch AM, the industry's first non-contact laser beam monitoring system for additive manufacturing. BeamWatch AM is a lightweight, compact system designed for real-time measurement of the focal shift during laser startup of powder bed fusion manufacturing processes.

It measures key beam size, position, and quality parameters, including focus spot size and beam caustic. These measurements allow users to more easily determine when the beam is aligned and in focus, providing more consistent metallurgy, MKS says. Measurements can be displayed as tabular, 2D, and 3D views, providing a quick display of laser characteristics.
