The new TR Scan Compact WLI range allows measurements on any type of material with sub-nanometric resolution.
With its simplicity of use and small size it integrates easily in a lab environment and permit to realize quick and simple measurements.
- Non-contact
- Small footprint
- Measuring range 400 µm
- Resolution 0.1 nanometer
- Extremely easy to use
- 2.5x and 5x Michelson type optics for a wide field of view
- Exchangeable optics, or mounted on a carousel
The table allows manual movement with workpieces weighing up to 5 kg.
Motorized tables are available as an option to extend the X&Y measuring range.
Mounting Bases
The table's thumbwheel allows precise movement in X & Y.
The Z-axis travel wheel has two functions: quick movement and fine positioning to easily adjust the working distance.

The piezo motor lifts the lens on the z-axis and the camera captures images in equidistant steps.
The image stack contains the information for calculating profile data from the surface.
Each independent pixel will have a so-called correlogram and the maximum variation of the sine light indicates a defined distance Z from the lens.
The extremely simple Trimos Compact WLI software allows fast measurement even by an inexperienced user.
In addition to the 3D analysis software, it is possible to carry out any type of analysis on the measurements taken.
Additional software module : Contour Basic & Advance
The contour module enables additional measurements to be made on the extracted profile, such as angles, distances, radius calculation, as well as the comparison of a DXF with the contour.
- Mirau objectives are used for higher magnification (10x; 20x; 50x; 100x)- Michelson objectives are used for lower magnification (2.5x; 5x)
- The objectives are exchangeable and this can be used to adapt the system to the necessary field of view and resolution
- Interference pattern will pictured if object and reference beam have the same length
The interferometry provides the extreme height resolution of 0.1 nm for all objectives (in contrary to other principles as confocal microscopy and focus variation)
