This approach is therefore faster than point-scanning or laser confocal systems. Furthermore, dual high-speed 5 MP, 200 FPS cameras generate nanometer-level 3D data at exceptional speed.

Class-Leading XYZ Resolution in Optical Profilometry

UP-3000's confocal technology delivers the most accurate XY resolution of any optical profilometry technique — even on steep slopes where other systems struggle. Its integrated interferometry mode adds industry-leading Z resolution at any magnification, uniting exceptional lateral detail with vertical precision in a single, powerful measurement platform.

5 Techniques, 1 Tool, One Click

The UP-3000 puts five imaging techniques at your fingertips — Confocal, White Light Interferometry, Dark Field, Variable Focus, and Bright Field — all in a single benchtop platform. With one click, instantly switch between modes to match your sample and measurement needs, eliminating the cost, complexity, and downtime of multiple standalone instruments.

Dark Field Imaging: See What Bright Field Can't

Dark field mode reveals surface cracks, defects, and features that vanish under conventional bright field illumination. Delivering high contrast, high resolution, and fast scanning, this capability sets the UP-3000 apart from most competing 3D surface profilers, uncovering critical details that would otherwise go undetected.

Measure Transparent, Translucent and Opaque Surfaces

The UP-3000's unique confocal mode conquers surfaces that defeat conventional optical instruments — glass, sub-surface features, microfluidic devices, multilayer coatings, polymers, and samples under liquid. Transparent, translucent, or opaque, no material is out of reach. Where other profilers fail, the UP-3000 delivers precise, reliable measurements every time.

Capture The 3D Profile From Any Material

The UP-3000 integrates Spinning Disk Confocal, White Light Interferometry, Dark Field, Variable Focus, and Bright Field imaging in a single optical head. Furthermore, switching between modes requires no hardware changes — one click selects the appropriate technique for the sample at hand. As a result, there is no need to move samples between instruments when measurement conditions change. In modern material science, many researchers choose a 3D optical profilometer confocal instrument to achieve high-resolution and accurate profiles across diverse sample types.

Fastest Confocal – Spinning Disk

The confocal module uses a spinning Nipkow disk with thousands of rotating pinholes that physically block out-of-focus light from the detector. The entire sample area is furthermore illuminated simultaneously, enabling full-area scans without XY stage motion. This approach is therefore faster than point-scanning or laser confocal systems. Additionally, it provides the highest XY lateral resolution for transparent layers, steep slopes, dark surfaces, and rough coatings commonly analysed by 3D optical profilometer confocal solutions.

Interferometry for Sub-Nanometer Roughness

The white light interferometry mode uses broadband illumination to generate interference fringes that encode surface height with sub-nanometer vertical precision. Both phase-shift interferometry (for smooth surfaces) and scanning white light interferometry (for rough surfaces) are furthermore available. As a result, the high-speed camera acquires interferometric data rapidly, therefore making surface roughness measurement and step height analysis fast and repeatable.

Dark Field Imaging Modes

Dark field imaging mode is particularly effective for detecting surface cracks, delamination edges, particle contamination, and micro-scale defects that are difficult to see under bright field illumination. The dark background created by the dark field optics furthermore makes reflective features at crack edges and surface discontinuities appear bright against the dark surround. As a result, this provides high-contrast imaging for quality control screening of coated components, glass substrates, and semiconductor wafers. For comprehensive defect detection, a 3D optical profilometer confocal approach ensures reliable and reproducible imaging. Consequently, individual defects can therefore be located and characterized with ease.

Variable Focus, Bright Field Imaging

Variable focus mode acquires a stack of focal planes and consequently generates an entirely in-focus 3D image across large Z ranges. Furthermore, bright field covers conventional optical microscopy needs without switching instruments.

Automatic Stitching

The UP-3000’s cross-roller XY stage performs automatic stitching across the entire sample surface. Furthermore, a single button press delivers a full 3D optical profiler image spanning multiple fields of view. As a result, no manual alignment is required. Notably, these capabilities are essential for a 3D optical profilometer confocal workflows in advanced laboratories.

Frequently Asked Questions

The UP-3000 measures surface roughness (Ra, Rq, Sa, Sq, and related parameters), step height, wear volume, 3D topography, and surface defects. In White Light Interferometry mode, it achieves sub-nanometer vertical resolution for smooth and specular surfaces. In Spinning Disk Confocal mode, it measures steep slopes, transparent films, and rough coatings that would cause fringe dropout in a pure interferometer. Dark field mode provides high-contrast images of cracks, delamination edges, and particles. The UP-3000 is a 3D optical profiler that adapts its measurement technique to the sample automatically.
The UP-3000 is used by researchers, quality engineers, and process development teams who need high-speed, non-contact 3D surface metrology. Coating and materials engineers use it to characterize surface roughness before and after deposition, verify film thickness by step height, and detect coating defects. Tribology and mechanical testing labs use it to map wear scars and scratch tracks after friction and adhesion tests. Semiconductor and display manufacturers use it for wafer surface inspection, PCB topography, and microelectronic feature measurement. The UP-3000 is suitable for both R&D and production QC environments.
The UP-2000 is a white light interferometer that focuses on WLI and phase-shift interferometry for roughness and step height on smooth to moderately rough surfaces. The UP-3000 adds Spinning Disk Confocal microscopy and Dark Field imaging, extending coverage to transparent films, steep slopes, and dark or highly textured surfaces. The UP-3000 also uses dual dedicated cameras and 4-color LED illumination, improving image quality across all modes.
Yes. The Spinning Disk Confocal mode handles transparent materials well because the pinhole array physically rejects out-of-focus light, including reflections from subsurface interfaces. This allows the surface topography of transparent coatings, optical lenses, and glass substrates to be measured without interference from back-surface reflections.
Yes. The UP-3000 comes with standard test protocols designed to support ISO 25178 areal surface texture analysis and ISO 4287 profile parameter measurement. The software calculates all standard roughness parameters in compliance with these specifications.
Dark field mode uses dedicated optics to create a dark background, so surface features that scatter light — cracks, particles, delamination edges, and surface discontinuities — appear bright against the dark surround. This high-contrast imaging makes defects clearly visible that would be difficult to detect under normal bright field illumination.
The Spinning Disk Confocal mode uses a Nipkow disk that illuminates the entire sample area simultaneously, rather than scanning point by point. The dedicated high-speed camera operates at up to 200 frames per second. This makes it significantly faster than point-scanning or laser confocal systems that require sequential XY motion to build a 3D image.
A confocal profilometer is a non-contact surface measurement instrument that uses a pinhole aperture to reject out-of-focus light. This enables high-resolution 3D topography mapping on reflective, transparent, rough, and steep surfaces that challenge standard interferometers. The UP-3000 uses spinning disk confocal technology — an area-scan approach faster than point confocal and free of the speckle artifacts of laser confocal systems.
The UP-3000 is designed exclusively for materials science, surface engineering, and industrial metrology. Its spinning disk confocal mode measures surface topography, roughness, and 3D structure on engineering materials — not biological specimens. It should not be confused with confocal microscopes used in life science or fluorescence imaging.
