  • 3D-L4000 with VisionPro

Optimize your product quality with high-speed, high-resolution 3D inspections

The 3D-L4000 with VisionPro combines laser triangulation with advanced image formation to create highly-detailed, three-dimensional renderings of parts under inspection. From these topographical renderings, you can capture precise measurements of every surface-level feature including length, width, height, tilt, and volume.

With a rugged, IP-65 rated design and a compact form factor, the 3D-L4000 with VisionPro easily fits into any production environment and offers manufacturers of all size:

  • A versatile solution to automate both 2D and 3D vision tasks
  • Full factory calibration to simplify deployment
  • Contrast independent inspection for higher detection capability

1 Only available when binning is enabled in the camera settings.

2 Z repeatability is measured an average of 100 times over a pointcloud using a 4x4 mm area, at the middle of the measurement range.

3 Z linearity is the maximum deviation of 250 position measurements on the measurement range, where a measurement is the average of 2 profiles using the standard Cognex target.

4 From the standard ambient temperature 21 °C (70 °F).

5 Mounted to a 400 mm aluminum bar along the camera’s fins (parallel to the camera) on top of the vision system.

6When binning is enabled and the FOV is windowed down.

Simplify complex applications without losing functionality

The 3D-L4000 laser displacement sensor is programmed using VisionPro software. VisionPro is a PC-based development environment that enables users to automate a wide range of functions, from inspection and identification to measurement and alignment. A full library of vision tools, combined with the intuitive QuickBuild interface, offers fast, flexible job configuration.

The easy-to-use QuickBuild interface provides a graphical approach to application development, allowing users to visually define and tune their application, without special programming or coding. Modular tool blocks allow users to create and reuse components, further simplifying setup and shortening cycle times.

For more challenging vision tasks, the QuickBuild interface offers advanced scripting and provides .NET C# programming options for additional flexibility in building custom applications or manually configuring jobs by code. 3D-L4000 with VisionPro is also compatible with Cognex Designer.
