Quality Assurance in Medical Technology

Precise measurement of complex medical components

In medical technology, complex geometries and functional surfaces must be measured and documented with high precision. Manufacturers are subject to strict regulatory requirements, including:

European Medical Device Regulation (MDR)
U.S. Food and Drug Administration (21 CFR Part 820)
Quality management systems according to ISO 13485

Optical 3D metrology helps manufacturers reliably inspect complex parts and provide reliable measurement data for quality documentation and process validation.

Contact-free measurement enables a full-surface analysis of geometry and surfaces – fast, reproducible, and with high resolution.

The µCMM measures outer and inner diameters, as well as form and positional tolerances, of components shorter than 10 mm in length.

Why Optical Metrology in MedTech?

Manufacturers of medical components face the challenge of reliably inspecting complex geometries and functional surfaces while meeting strict regulatory requirements.

Optical 3D metrology helps make manufacturing processes transparent and document measurement data in a reproducible manner—a key component of quality assurance and process validation.

Your benefits:

✔ Non-contact measurement of sensitive medical components

✔ Comprehensive analysis of geometry and surface structures

✔ High-resolution 3D measurement data for detailed quality assessments

✔Reproducible results for documentation and validation

✔ Support for regulatory requirements such as

Medical Device Regulation (MDR),
U.S. Food and Drug Administration (FDA), and
ISO 13485
