Features and Advantages
Principle: Laser Line Triangulation

QuellTech laser-scanners make use of the triangulation principle to detect the two-dimensional profile of surfaces. By means of particular optical components, a point-shaped laser beam is expanded to a line and projected to the object of interest. The diffuse light of the reflected laser line is captured by an objective at a certain angle and then directed to a two-dimensional receiver chip.

On the basis of distances and angles known, a precise calibrated height value (z) is calculated for each pixel in the x level (laser line), resulting in a precise profile in the x-z plane of the sample. If the scanner is guided over the sample (y axis), a series of profiles is created forming a three-dimensional point cloud in space. This point cloud can be subjected by dimensional control carried out by the software.

Q4 Laser Scanner, Compact Design with Low Shape Factors also for Complex Surfaces
The QuellTech laser scanners perfectly meet all requirements for a large range of measuring applications, allowing flexible integration even into difficult environment.  A particular benefit, compared to other laser scanner products, is their high stability against interaction with extraneous light.
  • X-Measuring Range from 4,5 to 650 mm
  • Z-Measuring range (Height) from 5,9 to 1000 mm
  • Laser wave length blue 405/450 nm, red 658 nm
Different optical power classes are available from 1 to 1400 mW. For optimum adaptation to the surfaces to be examined, the power class and wave length can be selected.
