Height gages have achieved a nearly universal presence in the quality control world. It is rare to see a QC department without at least one or two of these instruments. This commonality makes it easy to overlook just how accurate and flexible these devices are. They measure much more than the term “height gage” would imply.
In the world of automated industrial quality control and inline inspection, both 2D and 3D technology have important roles to play. In this three part blog series we will look at the strengths and limitations of each, and how combining the two creates a more complete inspection system.
Have you heard of Line Confocal Imaging (LCI)? Perhaps not, since the technology is relatively new to the already high-tech, high-resolution 3D measurement industry. Companies like Axiom Optics are dipping their toes in the water with STIL’s line of noncontact, chromatic confocal sensors.
Gage manufacturers and calibration laboratories often find themselves in this minefield. New gages or instruments are supplied or calibrated and immediately returned by the customer because they aren’t correct.
