Optical Comparator – Mitutoyo Optical Comparators

Explore Mitutoyo optical comparators and profile projectors for non-contact inspection of profiles, edges and dimensional features.

Non-Contact Profile and Dimensional Inspection

Mitutoyo optical comparators and profile projectors magnify a workpiece image so inspectors can evaluate profiles, edges and dimensional features without contacting the part. This approach is useful for small, delicate or complex components that may be difficult to check with conventional contact tools.

Contour illumination produces a clear silhouette for measuring outside profiles, while surface illumination helps reveal features on the face of a component. Depending on the system and accessories, inspectors can compare a projected image with an overlay, use digital readouts or connect measurement data to a processor or software workflow.

Applications and Selection Factors

Optical comparators are used for machined parts, stampings, cutting tools, threads, molded components and other workpieces with critical profiles or fine features. They can also support first-article inspection, tool verification and repeated production checks when a visual method provides the clearest way to assess the feature. The right configuration depends on the part dimensions, inspection tolerance, viewing requirements and operating environment.

• Screen size and magnification determine the viewing area and level of detail.
• Vertical and horizontal configurations support different part shapes and loading needs.
• Stage travel and load capacity must accommodate the workpiece and fixture.
• Illumination, digital readouts and data-processing options affect the inspection workflow.
