Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
How it works
The Contour GT system uses an optical metrology module (OMM) that splits light into reference and measurement beams to achieve interference. In VSI mode, a broadband white light source is used; the objective is translated vertically by an internal scanner while the camera captures frames. The height of each pixel is determined by the scanner position at which the modulation of the interference signal reaches a maximum.[2]
In PSI mode, a narrowband light source is employed. The system measures phase shifts in the interference pattern to determine surface height. PSI is typically used for smooth surfaces with roughness below 30 nm and provides sub-nanometer vertical resolution.[2]
The system includes a manual focus knob, a motorized Z-axis wheel, and a tip/tilt stage for sample alignment. Staging allows 150 mm of X and Y travel. The Vision64 software handles instrument control, data analysis, graphical output, and storage of results.[2]
Applications
VSI mode is effective for rough surfaces with adjacent pixel-height differences greater than 135 nm, yielding nanometer-range precision. PSI mode is used for smooth surfaces such as mirrors and polished optics, providing sub-nanometer vertical resolution.[2]

Frequently asked questions
What is the maximum sample dimension that fits on the stage?
The Contour GT-K systems come with staging that allows 150 mm (6 inches) of X and Y travel.[2]
What environmental factors should be controlled for optimal performance?
The Bruker Contour GT-K optical profiler systems use compressed clean dry air (CDA) for the vibration isolation system.[2]
What are the essential steps for a beginner to operate the Contour GT-K?
A beginner must become familiar with turning on and off the system, starting/stopping the Vision64 software, positioning a sample (placing the region of interest within the field of view, adjusting focus so fringes are visible, adjusting tip/tilt), selecting measurement parameters, and making a measurement.[2]
