The rigid carbon fibre based sensor structure offers a stable and protected support for all optical components ensuring high reliability in demanding conditions. Cognitens WLS400M is the only white light system to operate in hand-held mode with direct triggering.

The system is operated using a standard laptop which can be undocked for off-line operations in addition to serving as an analysis / reporting station.

The Cognitens WLS400 sensor features advanced LED (Light Emitting Diode) technology to allow highly reliable measurements in demanding conditions.

Cognitens WLS400 integrated LED technology provides:

• High intensity illumination source
• All illumination modules inside the optical sensor
• Increased system reliability and component lifespan
• Rapid triggering and image acquisition
• Enhanced system throughput
• Safe, low voltage electrical components
• Improved light uniformity for 3D surface measurements

White light technical priciple

The Cognitens WLS400 sensor projects a random pattern on the object and triggers a simultaneous capture of the area of interest by its cameras. The images are correlated using proprietary algorithms to create a 3D point cloud representation of the area. The sensor also acquires clear black-and-white images used for accurate measurement of specific features such as holes and edges. By combining sensor technology with CoreView software the system can generate a unified 3D inspection report for small to large objects.
