Machine Vision
Backlight
Backlight sources are placed behind the object to highlight its silhouette in a "shadow puppet" effect. These lights provide highly homogeneous, uniform, and diffuse illumination, eliminating reflections caused by the angle of light rays on the parts being inspected.

What types of backlighting products does Effilux offer?
Effilux designs LED backlight solutions tailored for industrial machine vision applications.
These systems are available in multiple configurations:
This flexibility enables Effilux to address both standard inspections and more complex vision systems.
- various sizes to match inspection areas
- formats compatible with machine integration
- adjustable intensity depending on application needs
- customizable versions for specific constraints
This flexibility enables Effilux to address both standard inspections and more complex vision systems.
How does a backlighting system work in an industrial application?
In a backlighting setup, the light source is placed underneath or behind the inspected object.
The light passes through or around the object before reaching the camera, which captures a high-contrast image. The object blocks the light, creating a clear silhouette.
This principle allows:
- precise edge detection
- accurate measurement of dimensions
- consistent image quality regardless of surface texture or color
What are the typical applications of backlighting?
Backlighting is particularly suitable for applications where shape and geometry must be analyzed with high precision.
Typical use cases include:
- dimensional measurement and metrology
- detection of presence or absence
- inspection of transparent or translucent parts
- edge and contour detection
- hole, cut-out, or profile inspection
What are the technical specifications of Effilux backlights?
Effilux backlighting solutions are designed to meet industrial performance requirements.
Depending on the configuration, they can include:
- a wide range of dimensions to cover different inspection sizes
- high light intensity for strong contrast
- wavelength options adapted to camera sensitivity (visible and specific needs)
- high uniformity to ensure reliable and repeatable measurements
