Lens & Optical Component Metrology
Compare Mahr solutions for evaluating lenses and precision optical components. Select the measuring principle around surface geometry, material and the manufacturing stage, from profile assessment to 3D evaluation.
What can you measure?
Optical surface roughness
Evaluate surface texture using a measurement principle suited to the optical material and coating. Confirm permissible contact and the required surface parameters.
Profile and areal form evaluation
Select 2D profile measurement or suitable 3D surface acquisition to evaluate the required optical geometry. Coverage depends on the lens shape, sensor and instrument configuration.

What to consider before choosing
Optical surface
Provide the nominal geometry, aperture, material, coating and drawing.
Measurement principle
Evaluate contact and optical methods against surface condition and permissible contact.
Evaluation output
Specify the required 2D profile or 3D evaluation, reference geometry and report.
Frequently asked questions
What information is needed to select a lens-measurement system?
Provide the optical drawing or nominal surface definition, aperture, material, coating and tolerances. Specify the manufacturing stage and whether the requirement is a 2D profile, 3D form evaluation or surface-texture assessment.
Should the lens be measured by contact or a non-contact method?
The choice depends on permissible contact, material, coating, surface slopes and the required evaluation. Compare the methods on representative optics rather than assuming that a non-contact approach is always suitable.
Can one setup cover several lens designs?
It may be possible, but the range of apertures, curvatures, surface types and fixtures must be reviewed. Share the full part family so changeovers, access and the required evaluation routines can be included in the proposal.
