Guides
//
Stylus or optical profiler
Learn when non-contact 3D metrology offers clear advantages over tactile measurement — from speed and flexibility to delicate surface inspection.
Micro or macro 3D profiling?
Find out how measurement scale, sample size and application requirements influence the choice of the right optical surface profiler.
Which optical profiler technology is the right one?
Compare key technologies such as WLI, confocal microscopy and focus variation — and understand which method best fits your surface.

Leak-tight catheters — measuring high-aspect-ratio step-height with telecentric optics
Catheter assemblies must seal reliably. See how telecentric optical profiling measures step heights deep inside high-aspect-ratio geometries without contact.
Manufacturing of 3D metal printed parts optimized with macro profiling
In metal 3D printing, hidden defects can compromise entire parts. See how large-area optical profiling helps keep safety-critical production processes under control.
Ensuring highest quality of micro-optical components with WLI inspection
Tiny, mirror-flat thin-film filters push standard microscopy to its limits. See how WLI inspection ensures the optical quality of micro-components.
Heavy-duty engine manufacturer cuts failure rates with an macro profiler
A press-fit component failed more than half the time. See how optical macro profiling revealed the root cause and improved process reliability.
How macro profiling stopped seals from leaking
A sealing face may look flat and still leak. See how non-contact optical profiling detects the micron-level deviations that decide sealing performance.
