Specialized lighting creates all-important contrast between the feature of interest and its background.
Area Lights provide even illumination in a concentrated area. Well-placed area lights can create shadows and glare, allowing the vision sensor to detect the presence or absence of a feature.
Ring Lights provide diffused illumination over a small area. With the lens axis through the center opening of the ring light assembly, the ring light illuminates the area directly in front of the camera.
Backlights provide even, low-intensity light. It is placed behind the target and aimed directly back towards the camera. The resulting silhouette can be inspected for proper size and shape.
Spot Lights provide extremely bright, even light with a single high-powered LED. Well-placed spot lights can create shadows and glare, allowing the vision sensor to detect the presence or absence of a feature.
On-Axis Lights provide even, diffused illumination for flat, reflective surfaces. A beam splitter directs the light rays along the same axis as the camera lens. Reflective surfaces perpendicular to the camera appear bright. Surfaces at an angle to the camera and non-reflective surfaces appear dark.
Tubular Fluorescent Lights
Tubular Fluorescent Lights provide easy, affordable, flicker free illumination of large objects.
Highly Diffused Lights
Highly Diffused Lights illuminate a target from many directions, eliminating shadows or glare.
