Industry’s desire for accuracy evolved with the integration of computer technologies including hardware and software however, one of the first instruments that helped things along was the early invention of the optical comparator for inspecting manufactured parts.
The model depicted is a Japanese product by Mitutoyo Corporation and incorporates some of the latest advances including integrated computer digital readout of the part being viewed.
An optical comparator, as you may already have deduced even if you are not familiar with them, is an inspection machine using optics to magnify parts where the magnified silhouette of part projected onto a large screen like the one shown allowing accurate two-dimensional measurements.
These machines save time in set up and parts handling because their of ease-of-use and ergonomic designs allowing quick worker training reducing overall inspection time.
Optical comparators are also relatively inexpensive considering the amount of accuracy they provide even the low-end of the scale models costing the least amount of just a few hundred dollars or depending on the level of sophistication those costing thousands of dollars.
