Frequently asked
What we measure optically
Where probing reaches its limits, we measure without contact and evaluate to standard.
Non-contact capture of inspection characteristics
Tactile and optical sensors combined in the same inspection plan
Characteristics evaluated to drawing and ISO GPS
Traceable method choice per characteristic
Mitutoyo QUICK VISION Apex Pro 404 with TP20
Resolution
optical in the sub-micrometre range, full-surface 2D/3D measurement with a high-resolution camera
Sensors
Renishaw TP20 probing system as a tactile complement for hard-to-reach geometries
Multi-sensor
optical for fast surface inspection, tactile for precise geometries, in the same inspection plan
Evaluation
per ISO GPS or ASME Y14.5, suitable for delicate, small and complex parts
Software
QVpak — CAD-based programming, combined optical-tactile evaluation, reports as Excel or PDF

What customers ask about optical measurement
Which parts is optical measurement suited to?
Flat and small parts with many contours, edges and holes: stamped, turned and milled parts.
What is the advantage over tactile measurement?
Speed with many characteristics, and non-contact capture: no probing, no force on the part. For spatial characteristics and deep bores, tactile measurement remains superior.
Does the surface matter?
Yes. Glossy, transparent or very dark surfaces can make edge detection harder. We check this on the part and choose lighting and method accordingly.
Are the optical measuring machines calibrated?
Yes. The Quick Vision is calibrated by an SCS-accredited partner (ISO/IEC 17025), directly in our measuring room — with a calibration certificate and traceability to the national standards (SI). What a calibration proves (German) →

Send us your measurement task by email
Briefly describe the part and what should be inspected, and attach the drawing or CAD data — excerpts are fine. An NDA before the first file is available on request. You normally receive a reply within one working day, in English if you prefer.
