LDD's LD-600 product line uses optical depth measurement sensors to provide precise depth measurement and images in real time during industrial laser processes, allowing for real-time quality control and closed-loop operation. The sensors use a low-power IR laser beam to gauge distances and images, and readings are accurate even while the laser is operating. The technology enables industrial manufacturers to improve in-process development, productivity, and cost minimization for applications such as welding, drilling, and micro-machining.
