An optical profile projector, also known as an optical comparator or profile projector, is a precision measuring instrument used for inspecting and measuring the dimensions and contours of small parts. It works by projecting a magnified image of the object onto a screen, allowing operators to compare the part’s profile with predefined standards or specifications. The optical profile projector is widely used in quality control and manufacturing processes to measure complex shapes, angles, and dimensions with high accuracy. It is commonly utilized in industries like automotive, aerospace, and precision engineering for inspecting mechanical components.
