Optical Comparators

Optical Comparators

The optical comparator has been a staple in the manufacturing environment since the 1920s. It’s a tried and true technology because of its familiarity and simplicity. While it is being replaced in some applications by more sophisticated vision measurement equipment, the optical comparator still has its place in the manufacturing environment.
