Optical Dimensional Measurement
Compare Mahr optical dimensional-measurement instruments for visible edges and geometric features. Evaluate measuring microscopes and automated variants around the part, illumination and inspection sequence.
What can you measure?
Diameters, radii and angles
Evaluate geometric elements from optically detected edges. Select illumination and magnification that provide reliable edge contrast on the actual component.
Small and contact-sensitive features
Inspect accessible geometry where contact probing could deform or obstruct the feature. Suitability depends on optical access, surface response and the required dimensional tolerance.
Models and measurement options

| Other 2D / 3D optical configurations | Application-based selection | Confirm the sensing method and available configuration for the required dimensions. |
Ranges refer to specific variants or sets. Confirm the exact model, configuration and accessories with your quotation.
What to consider before choosing
Edges and lighting
Provide the material, finish and features to be detected. Evaluate illumination on the real component.
Travel and access
Compare the part envelope, fixture space and measuring range; nominal travel alone is not the usable inspection envelope.
Manual or CNC
Describe batch size, operator workflow, program reuse and reporting requirements.
Frequently asked questions
Should I choose a manual or CNC measuring microscope?
A manual workflow may suit varied, lower-volume checks; CNC should be evaluated when repeated inspection sequences and program reuse are important. Compare both against the number of features, part mix and required throughput.
Which MarVision MM 500 measuring range do I need?
The listed M, L and XL variants provide 200 × 100, 300 × 200 and 400 × 250 mm X/Y ranges. Allow for the fixture and the travel needed to reach every feature, not just the component’s overall size.
Will the microscope reliably detect the edges on my part?
Edge detection depends on material, surface finish, lighting and geometry. Provide a sample or clear images identifying the features, especially for reflective parts or poorly defined edges, so the illumination and measurement method can be assessed.
