Optical surface measuring systems
Fast contour and roughness measurements
It’s no longer enough for many workpieces these days to collect dimensional measurements. More and more, it’s necessary to collect the entire two- or three-dimensional topography of a surface. With the services of optical measuring technology, point clouds are created with extremely high point density. The resolution that this enables is suitable for being able to evaluate even the smallest geometries.
For larger and flat measuring ranges in particular, optical measuring technology is an advantage because it allows measuring to proceed much more quickly.
By doing so, measurements can even be made directly against a CAD model – and a two-dimensional display of the deviations can be rendered in close to real time. These results allow for fast conclusions on the production process and enable short reaction times up to closed control loops.
Another advantage of optical measuring technology is that workpieces and their surfaces can be measured without contact so as to avoid damaging them with the measuring probe. This is relevant to sensitive plastic and mirror surfaces, for example.
