An optical comparator, also known as a profile projector, is a tool that uses the principles of optics to analyse produced parts. It is frequently referred to as merely a comparator in context. In a comparator, a part’s magnified silhouette is displayed onto the screen, and its dimensions and geometry are measured in comparison to predetermined standards.
It is a valuable tool for the quality control inspection team in a small components machine shop or manufacturing line.There are various methods for measuring. The simplest method is where the observer may measure as if a clear ruler were set over the image thanks to graduations on the screen projected over the silhouette.
Another method involves moving the stage on which the part is mounted. A digital readout then shows how far the stage has to move to align each point on the silhouette with the reticle at the screen’s centre.
The most cutting-edge techniques also use software to analyse the image and produce measurements. The first two techniques are the most widely used; the third is more recent and less popular, although their uptake is continuing in the digital era.
The profile projector is frequently used to compare the measured contour model and for complex-shape stampings, gears, cams, and threads.
The profile projector is therefore frequently used in the production of precision machinery, especially in the fields of aviation, aerospace, watches, clocks, electronics, instruments, research institutes, and detection metering stations at all levels, among others.
On the built-in projection screen, the projector enlarges the specimen’s profile for viewing. In order to match the screen’s X-Y axis with a straight edge of the machined component for inspection or measurement, this screen often has a grid that can be rotated 360 degrees.
For more ease in calculating linear measures, this projection screen shows the specimen’s profile and is magnified.

Notre Dame Opens Engineering Innovation Hub.The University of Notre Dame has launched an experiential learning and advanced manufacturing facility that, according to the university, will enable increased cooperation, fabrication, robotics, and modelling. Notre Dame’s iNDustry Labs include the 10,000-square-foot Engineering Innovation Hub.
According to Notre Dame, the EIH will also function as a research fabrication and testing facility, as well as a resource for local manufacturing industry partners and startups.
It is located on the first floor of the Cushing-Fitzpatrick Halls of Engineering and is equipped with fabrication and machining equipment, sophisticated manufacturing stations, 3D printing stations, and computing resources.
This extraordinary facility will aid in the preparation of future engineers who are not only technical specialists, but also people who use creativity and innovation throughout their careers and to assist a world in need.
Notre Dame’s Engineering Innovation Hub (EIH) is a one-of-a-kind learning and innovation environment on the first floor of Cushing-Fitzpatrick Halls of Engineering, providing tools for collaboration, fabrication, automation, robotics, and modelling to students, faculty, and industry partners.
The EIH combines specialised collaborative space with cutting-edge technology and experience in areas such as advanced manufacturing, additive manufacturing (3D printing), metrology and computer resources, and fabrication and machining technologies.
The EIH is part of Notre Dame’s increasing ecosystem of experiential learning spaces that fosters innovation and the exchange of best practices among students, faculty, and industry partners.The EIH is happy to provide a regional resource for developing creative product solutions for existing businesses as well as fresh start-ups.
