Cognitens WLS400M - Manually operated white light scanner
Manually operated white light scanner
The Cognitens WLS400 is the next generation of Hexagon Metrology White Light sensors featuring the latest technologies including high-resolution digital cameras, LED-based illumination, carbon fibre structure, and rapid data-acquisition and processing.
The Cognitens WLS400M white light scanner is a manually operated system used for 3D metrology, quality inspection and digitizing. The system features unique measurement capabilities which emphasize its value for multiple industrial applications.
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.
