Machine Vision Backlights

Backlights are essential machine vision illumination solutions designed for silhouette imaging, dimension measurement, and defect inspection. Contrastech offers Bottom Flat Backlights and Side Flat Backlights, providing uniform area illumination through different LED arrangements to meet various inspection requirements.

Bottom Flat Backlights use LED beads distributed on the bottom for consistent backlighting, while Side Flat Backlights feature LEDs placed on the inner sides for flexible illumination of different objects. They are widely used for dimensional measurement, visual inspection, liquid level detection, pinhole inspection, metal burr detection, and packaging defect inspection.
