Optical Profilometers
Optical Profilometers
Profilm3D® and Zeta™ optical profilometers provide fast, easy, non-contact solutions for 3D surface topography measurements. Our portfolio of optical profilers supports a variety of measurement techniques, including white light interferometry, True Color imaging and ZDot™ confocal grid structured illumination. KLA Instruments can help guide you to the right profiler solution for your unique needs.
Filmetrics® Profilm3D® Optical Profilometer
The Profilm3D® benchtop optical profiler utilizes white light interferometry, TotalFocus™ infinite depth-of-field imaging, or Enhanced Roughness Mode to provide easy, non-contact measurement of 3D step heights, roughness, and other surface topography.
Zeta™-20 Optical Profiler
The Zeta-20 benchtop optical profilometer features patented ZDot™ technology and flexible multi-mode optics for measurement of 3D surface topography, film thickness and automated defect inspection.
Zeta™-300 Optical Profiler
Building upon the proven performance of the Zeta-20, the Zeta-300 optical profiler includes integrated vibration isolation and support for larger sample sizes to meet your R&D and production requirements.
Zeta™-388 Optical Profiler
The Zeta-388 optical profiler combines the Zeta-300 system with a cassette-to-cassette wafer handler, pattern recognition, automated data analysis and SECS/GEM to support production measurement requirements.
