Chromatic Focus Line Sensor CFL

Highly accurate chromatic line sensor

Benefits

The Chromatic Focus Line sensor allows extremely fast capture of measured values with up to one million measurement points in less than three seconds thanks to a linear arrangement of lots of chromatic sensors. The chromatic measuring principle ensures low measurement errors and is largely independent of the surface properties. Areas of application include diffusely reflective as well as reflective and transparent workpieces.

Please accept "Other" in the settings to watch this video. Other benefits

Adaptation of measuring uncertainty and measuring range to the respective application with different lenses
Due to a large axial measuring range, it is often not necessary to adjust the device axes to the workpiece geometry
The ability to quickly create a raster image of the workpiece surface allows the formation of local coordinate systems for further measurements with other sensors
Coating thicknesses of transparent materials can also be measured (optional)

Technical Data

Optical-axial (chromatic aberration)

0.2 mm to 4 mm

Permissible probing deviation up to 1 µm

The light from a broadband light source b) is projected from the evaluation box a) onto the workpiece (position 1), 2) or 3)) via fiber couplers c), optical fibers arranged in a line d) and imaging optics e). The intensity of the reflected light is highest for the color that corresponds to the distance from the workpiece f). This is evaluated simultaneously for all measurement points on a line using a spectrometer g).
