About Unilux
Unilux Inc., headquartered in Saddle Brook, New Jersey (USA), develops and manufactures stroboscopic inspection systems for industrial quality control. The LED strobes visually 'freeze' fast-moving webs, enabling inspection of surfaces, print quality and strip edges at full production speed – from portable battery-powered devices to permanently mounted systems for surface widths up to 12 m. The portfolio includes the LED strobe series (including LED-250, LED-2000 with Smart Assist and Cross Light Inspection), the camera-based print monitoring system UniPRINT (18x zoom, split screen, UV inspection) and the edge inspection system Edge Tech with Supervised Machine Learning for automatic defect detection on steel strip. Unilux has more than 60 years of experience in the steel, paper, printing, converting and film industries and is present worldwide with five direct sales offices (USA, China, Germany, India, Thailand), six service centers and sales representatives in 58 countries. The sales office in Düsseldorf is responsible for the DACH region.
