Using newly developed and recently patented technology, Cognex eliminates the speckle effect of laser lines, optimising triangulation-based 3D imaging. The In-Sight 3D-L4000 embedded vision system is the first product to bring the benefits of speckle-free laser lines to users. In applications such as 3D inspection of castings, the speckle-free laser line enables more accurate results than other 3D imaging systems.
