METROLOGY
Digital comparators combine the best features of optical comparator and vision system technology. REQUIRE THE RIGHT METROLOGY SOLUTION MEDICAL MANUFACTURERS
By CW Moran
T he modern medical device industry is subject to some of the most stringent and demanding manufacturing standards in the world, as well as tight delivery timelines. Virtually every aspect of each part is tracked and inspected for quality, requiring 100% inspection assurance and part traceability. As a result, an efficient quality control (QC) department is critical, requiring equipment that’s dependable, accurate, fast, and easy to operate. Traditionally, when selecting a metrology system solution, compromise has often been the norm – either choose optical systems for their reliability, ruggedness, and familiarity, or choose vision systems for speed, accuracy, and convenience. Users rely on optical com-
parators because of their ease of use and established track record. Comparators provide a combination of excellent image quality and a full range of features. These include superb optics, readout devices, software interfaces, and geometric measuring capabilities. While the basic components of a comparator have remained the same – such as lights, mirrors, and lenses – construction and functionality have increased. Modern comparators are built to withstand practically any harsh conditions found in a manufacturing facility. The body of the comparator is usually a sealed, all- metal construction to keep out the elements. The stage is wear-resistant to hold up against constant, repeated use, and a range of compatible accessories and readout options make stock comparators flexible and highly customizable. For these reasons, combined with their
