As products get ever smaller, new geometrical characteristics that weren’t quite as important in larger dimensions are influencing product functionality. Surface properties are very important when it comes to improving functions such as high-precision motion, automatic assembly or components’ service lives. This is particularly true in precision engineering. Only the right application allows you to manufacture parts with an extended service life for precision mechanics. Last but not least, optical measuring technology is steadily gaining in importance in quality assurance operations for fine and microtechnology products due to its short measuring times, high resolution and contactless, non-intrusive measurement principle.
