Optical imaging sensor CFZ

Highly accurate measurements without sensor misalignment in all three spatial directions The combination of several sensors into one multi-sensor offers increased ease of use and measurement time savings due to the elimination of sensor change cycles. With the different sensor principles, the patented CFZ has a high degree of flexibility. Due to the absence of sensor offset, a smaller and thus more cost-effective measuring machine can often be used. • Low measurement errors due to high magnification range of the telecentric zoom optics • Intelligent contour image processing detects multiple geometric elements and free forms in the measuring window • Distance measurements largely independent of surface properties due to the chromatic measuring principle • Fast sensor change without mechanical movement • Large measuring range of the chromatic sensor enables fast scanning without moving the sensor to the workpiece surface and thus even shorter measuring times • Layer thicknesses of transparent materials can also be measured (option) Measuring range 1 mm Accuracy Permissible probing error up to 0.75 µm Functionality From the evaluation box a) the light of a broadband light source b) is projected via a fibre coupler c), an optical fibre d) and an imaging optic e) onto the workpiece (position 1), 2) or 3)). The intensity of the reflected light is highest for the colour corresponding to the distance from the workpiece f). This is evaluated via a spectrometer g). Via a divider mirror h) the additional integration of an image processing sensor i) (illumination not shown) takes place.
