Vision lighting is the key to creating all-important contrast between the feature of interest and its background.
An area light provides 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.
Linear array lights provide high-intensity illumination of large areas, at long distances.
A ring light provides 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.
A backlight provides 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.
A spot light provides 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.
Linear array lights provide high-intensity illumination of large areas, at long distances. Available in 3 housings: nickel-plated aluminum (IP68), stainless steel (IP68) and black anodized aluminum (IP50).
Low-angle vision lighting enhances the contrast of surface features. The low-angle light is aimed nearly perpendicular to the imaged surface of the target object, casting shadows that emphasize changes in elevation.
On-axis vision lighting provides 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 ...
The LLG660 generates a high quality, uniform laser line, making it especially suitable for machine vision applications.
