Metrology-Grade Performance
On Challenging Surfaces and Material Types

High-Precision 3D Scanning and Measurement
For a Wide Variety of Challenging Material Types

FocalSpec LCI sensors scan down to 2.1 microns X resolution and 0.11 Z repeatability for unparalleled measurement precision on many challenging materials, including curved display glass, multi-layered transparent materials, and shiny metallic surfaces.

3D Tomographic Imaging
For Detecting Material Surface Layers

FocalSpec LCI sensors contain embedded fast signal processing units, which detect all the surface layer 3D profiles in the tomographic images. Height information of each measured data point is then processed in calibrated micrometers.

Precision Defect Detection
Precision Defect Detection
For 100% Quality Control

The combination of 3D tomography and 2D intensity imaging can be used for identifying defects such as delamination, scratches, or dust on the surface or inside laminated glass, mobile phone displays or any other type of transparent multilayered material.

Excellent Surface Angle Performance
Excellent Surface Angle Performance
For Scanning and Measurement of Curved Edges

FocalSpec sensors are able to capture the profile of curved display glass at a surface angle of up to 20 degrees (e.g., for scanning 2.5/3D display glass). In case of higher angles, the sensor or the sample can be tilted or the sample can be captured with another FocalSpec sensor.
