We are a leading global provider of machine vision products and solutions that improve efficiency and quality in high-growth-potential businesses across attractive industrial end markets. Our solutions blend physical products and software to capture and analyze visual information, allowing for the automation of manufacturing and distribution tasks for customers worldwide.

Machine vision is important for applications in which human vision is inadequate to meet requirements for size, accuracy, or speed, or in instances where substantial cost savings or quality improvements are maintained.
