Cognex Machine Vision Lighting Catalog

Consistent lighting gives vision systems and barcode readers a clean image to work from. Cognex lighting works seamlessly with our systems and adjusts in intensity for stable, repeatable results.

• Glare on shiny, curved parts: Dome lights diffuse light from all directions to minimize reflections
• Shadows on flat, reflective surfaces: Coaxial lights shine along the optical axis to minimize them
• Edges lost against the background: Back lights create high-contrast silhouettes for gauging, void detection, and alignment
• Long parts, edges, and seams: Bar lights give uniform coverage, angled for bright-field or dark-field
• Holes, threads, and small components: Ring lights provide even illumination around the lens
