Color is our perception of reflected light across the visible spectrum. When light hits an object, it absorbs some rays and reflects others. The color of light that reflects back into our eyes is the color we perceive. The more light an object absorbs, the darker it appears.

For more than 50 years, the benchmark for accuracy in measuring solid objects, whether machined, molded, die-cast, welded, or forged, was the coordinate measuring machine (CMM). Typically using a solid-granite base table, along with a vertical, horizontal, gantry, or bridge-mounted arm as well as a touch probe, measurements would be taken and compared in blocks to an engineering file, first as 2D drawings and today as CAD files hosted in the cloud.

High-volume manufacturers need fast, nondestructive testing methods to help avoid material mix-ups and to meet customer quality requirements. Quality assurance (QA) inspectors are responsible for evaluating incoming raw materials by determining their elemental makeup and assessing the structural integrity of products on the production line. QA inspectors need a reliable solution that helps them get both jobs done, quickly and efficiently.
