Overview
The Cognex In-Sight L38 is a 3D vision system that combines embedded AI, 2D imaging and 3D depth perception in a single smart camera. Rather than needing an external PC and bespoke programming, it runs AI tools on board and can be trained with as few as five to ten labelled images, which shortens the setup time on a production line.
Its patented speckle-free laser optics capture higher-resolution images than traditional laser displacement sensors, while a high-powered Class 2M laser supports fast acquisition at high line speeds without the cost of a protective enclosure. The L38 builds projection images that fold 3D depth into a single, easy-to-label 2D image, so AI tools can detect variable or complex features that 2D vision misses.
The family spans several working ranges. The short-range ISL38-100 resolves detail down to 39.1 µm in X and 4.4 µm in Z with 1 µm repeatability, while the long-range ISL38-500 covers larger fields at coarser resolution. All models share the same 1920-pixel imager and aluminium housing, and the L38-xxx variants add VisionPro for more advanced 3D measurement and robot-guidance workflows.
Key Benefits
Embedded AI trains from just 5-10 labelled images, with no external PC. Speckle-free laser optics deliver cleaner 3D data than conventional laser displacement sensors. Class 2M laser avoids the cost of an enclosure. 2D + 3D in one platform solves inspection, measurement and robot guidance together.
Applications
Inline quality inspection and assembly verification, robotic guidance and bin picking, precision dimensional measurement, surface and defect detection, and 3D measurement tasks from component-level detail to large-part fields of view.
