Machine Vision Bar Lights
Use bar lights when illumination angle must 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.
Best fit
- 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
