When to use back lights and where to place them

back lights and how to adopt them

Back light illumination places a bright, luminous surface opposite the camera with the target object placed in the beam path between the illumination and the camera. This makes outlines visible and measurable with great precision due to the maximum contrast achieved with backlighting.

Backlighting avoids uneven contrast in complex object shapes, which can occur with many other types of lighting.

Contrast is strongest for opaque or partially opaque objects—a benefit for stable quality control.

Application example: contour and dimension measurements, foreign object inspection, fill level control, inspection for burrs.
