How to Choose an Optical Measurement Projector
The primary choice is between vertical and horizontal projectors. Choose a vertical projector (light path travels vertically) for flat parts like gaskets, O-rings, and stamped components, as parts are simply placed on a glass plate . A horizontal projector (light path travels horizontally) is better for large, heavy parts like shafts, castings, and machined components, which are typically held on V-blocks or between centers .
