chromatic confocal sensor / for transmission measurement / for thickness measurements / non-contact

The new compact sensor measures distances and layer thicknesses ultra-accurately and at high speed. The CHRocodile C’s revolutionary design integrates opto-electronics and measuring probe in one single housing the size of a pack of cigarettes. With its four newly-developed optical probes that can be easily replaced by the user, the system can be parameterised within wide limits and adapted to the measuring Task.

The new CHRocodile C sensor is also the smallest-ever “all-in-one” point sensor from Precitec Optronik. When ready for use, the chromatic confocal measuring unit consisting of sensor and optical probe weighs only 440 grams. The probes can also be replaced without the need for tools. There are no other setting controls on the system unit itself – LEDs provide information about the status and operational readiness of the measuring system. The triggerable system has a sync output and standard Ethernet and RS422 Interfaces.


With its compact housing, the CHRocodile C is eminently suitable for in-process quality control procedures and is ideal for integration with automatic optical inspection machines. Its high dynamics and outstanding signal-to-noise ratio allow measurements to be performed on a wide range of surfaces. The CHRocodile C’s robust and non-contact measuring system is maintenance-free and easy to integrate into inspection machines.

With its compact design, contact-free measuring principle and excellent price-performance ratio, the CHRocodile C is the ideal alternative to classic laser triangulation sensors.
