Question

Quizplus · Accepted Answer

An optical comparator is a machine that projects a magnified image of a part onto a screen for measurement. It is commonly used in manufacturing and engineering to ensure that parts are made to specifications. Telescoping gauges are used to measure the inside diameter of a hole, sine tools for measuring angles, and profilometers for measuring surface roughness.
