Vertical profile projectors, also known as vertical optical comparators or shadowgraphs, are optical instruments used for non-contact measurement and inspection of two-dimensional profiles and features of a test specimen. They are commonly employed in industries such as manufacturing, toolmaking, and quality control to assess the dimensional accuracy and form of parts.
Optical comparator typically consist of a projection system, a precision stage for holding the test specimen, and a projection screen or glass. The instrument projects the magnified image of the specimen onto the screen, enabling the operator to visually compare the projected profile with a reference or template. These projectors may include profile illumination options, such as surface or backlight illumination, to enhance the visibility of the specimen’s features. Some advanced models also incorporate edge detection software or digital image processing for automated measurement and analysis. Vertical profile projectors provide a quick and reliable method for assessing the form, contours, and dimensions of parts, aiding in quality control, reverse engineering, and dimensional inspection tasks.
