CHRocodile 2 DPS


The chromatic confocal sensor CHRocodile 2 DPS is equipped with two independent measuring channels, which allow simultaneous measurements at full measuring rate. The embedded processor of the sensor receives the respective data, synchronises it and outputs corresponding thickness or step height values ​​directly. This makes the CHRocodile 2 DPS the ideal device for double-sided thickness measurement of non-transparent or very thick materials that can no longer be measured with just one measuring head. In addition, the CHRocodile 2 DPS is a cost-effective measuring system, replacing two single-sensor systems.

CHRocodile C

The ultra-compact CHRocodile C sensor combines opto-electronics and optical measuring head in a compact system housing and enables highly accurate distance and thickness measurements.

CHRocodile C is ideal for in-process inspections and is easy to integrate into in-line inspection machines.

The exceptionally high dynamics and excellent signal-to-noise ratio make the CHRocodile C optical sensor the first choice as a measuring instrument for all materials.

With its compact design and excellent value for money, the CHRocodile C is the ideal alternative to traditional laser triangulation sensors.

CHRocodile 2 S / 2 SE

The new generation of proven CHRocodile sensors offers an unsurpassed high speed of 66000 measurements / second. The optical sensors work with white light and are perfect for the non-contact detection of topography and layer thickness.

The exceptionally high dynamics and the excellent signal-to-noise ratio ensure the best measuring results, even on surfaces with different reflections. The sensors can be switched from chromatic-confocal to interferometric measurement technology.

Universally applicable in quality assurance and production.
