- Characteristics -
The backlight sources are placed behind the part to highlight the outline of object.. These lightings offer a very homogeneous, uniform and diffuse light while minimizing the reflections of the object.
- Applications -
- Highlighting the silhouette of the object (maximum contrast between the background and the form) for dimension control
- Inspect absence / presence of holes
- Ideal for transparent and translucent materials (glass, fabric, printed circuit...)
- Liquid level control of bottle
- Many other machine vision applications.
