By projecting a magnified shadow or image of your part onto a screen, these optical comparators give you an easy way to measure and inspect its precise features. They work similarly to overhead projectors, but with fixed magnification to preserve proportions. An optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection of manufactured parts. In a comparator, the. Utilize automated tools and optical measurement systems to minimize human error, streamline processes, and ensure consistency. Start system configuration by selecting a stage size (small, medium, or large) that matches your part's physical dimensions. They combine to ensure bright, sharp images and exceptional. The LM393B and LM2903B devices are the next generation versions of the industry-standard LM393 and LM2903 comparator family. These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation. Our VisionGauge® Digital Optical Comparators streamline your manufacturing process by capturing images of manufactured parts and automatically comparing them to their CAD drawings. Because of how easy they are to set up.
