Coherix 3D Mini™

A New Way of Inspection.

In manufacturing today, application of adhesives and sealants must be precise to achieve full performance and power. Coherix 3D Mini provides inline 100% robust 3D inspection of the bead as it is being dispensed. It tells how much and where the bead is dispensed at any instantaneous moment.

Coherix 3D Mini measures height, width, volume and location, providing the vital data needed to optimize the dispensing process for micro bead geometries from 0.2 – 3.5mm without the need for an additional computer. Coherix 3D Mini bead inspection, mounted around the dispensing nozzle, is equipped with four high-speed 3D sensors, providing a 360° view of the bead in any dispensing direction, with no added complexity to robot programming. Manufacturers of automobiles, consumer electronics, medical devices, industrial electronics, automotive electronics and general industry benefit from the part traceability with flexible archiving options provided by Coherix 3D Mini.

Once and done

Single-pass 3D bead profile inspection is accomplished using four high-speed laser sensors leading and trailing the dispensing nozzle to track and inspect the bead when applied in either forward or backward direction with no blind corners. Acquiring and processing 400 samples per second, Coherix 3D Mini has industry-leading acquisition speed avoiding production slow-downs.


Coherix 3D Mini leverages a 3D high-speed imaging and processing platform that has proven reliability, inspecting millions of customer parts to date. In addition, Coherix 3D technology has been widely deployed for bead inspection for numerous applications including powertrain RTV, body shop structural adhesive and sealants, final assembly urethane glass, battery thermal paste, glass primer, battery cover sealant and more with OEM and Tier suppliers globally.

Easy to integrate

Coherix 3D Mini mounts around the dispensing nozzle. It communicates easily with whatever protocol your dispenser or robot uses. Coherix 3D Mini inspection does not add complexity to robot programming. There are no time-consuming setup changes required for robot speed changes commonly necessary on other systems.
