Machine Vision Bar Lights
Use bar lights when illumination angle needs to be tuned. A bar light can reveal edges, scratches, embossing, texture, and shape by changing the direction and height of the light relative to the camera and workpiece.
Suitable uses
- Directional surface defect inspection
- Large fields of view
- Oblique lighting for texture
- Multi-side lighting around fixtures
Likely to fail when
- The target needs shadowless illumination
- Glare is uncontrolled on polished surfaces
- Mounting space cannot support the required angle
Selection inputs
- Emitting length
- Working distance
- Angle and number of bars
- Diffuser or polarizer requirement
- Line speed and strobe power
Frequently asked questions
When is Machine Vision Bar Lights useful?
Use bar lights when illumination angle needs to be tuned. A bar light can reveal edges, scratches, embossing, texture, and shape by changing the direction and height of the light relative to the camera and workpiece.
What information is needed to select a light?
Start with Emitting length, Working distance, Angle and number of bars. Share target images and the inspection requirement so the arrangement can be checked on the actual application.
