- Characteristics -
The backlight sources are placed behind the part to highlight their figure into "shadow". These lightings offer a very homogeneous, uniform and diffuse light, avoiding the reflections generated by the incidence of light rays on parts to control.
- Applications -
- Highlighting the silhouette of the object (maximum contrast between the background and the form)
- Dimensional control and the absence / presence of holes
- Control of transparent and translucent materials (glass, fabric, printed circuit...)
- Liquid level control in a bottle
