3D Optical Profiler

Bruker - Contour Elite K

Royce Discovery Centre | University of Sheffield

The Contour Elite K is a 3D optical profiler that uses white light interferometry for precise, non-contact surface measurements. It offers nanometer-scale resolution for rapidly analyzing roughness, texture, and step heights.

Description

The Bruker Contour Elite 3D optical profilometer employs non-contact white light interferometry (WLI) technology, operating in both Vertical Scanning Interferometry (VSI) and Phase Shifting Interferometry (PSI) modes. This non-invasive method rapidly measures surface topography with high resolution, accommodating a wide variety of sample types and sizes. It can be used to examine a wide range of samples from 0.05% till 100% reflectivity, flat to rough and slopped surfaces, providing accurate measurements plus high-fidelity imaging. The system generates detailed 3D surface profiles for comprehensive material property analysis. With user-friendly software that simplifies setup and data interpretation, the Contour Elite is an essential tool for precise, efficient surface characterization in both research and industrial environments.
