Machine Vision Ring Lights
Use a machine vision ring light when the camera views the target from the front and the inspection needs compact, even illumination around the lens. Ring lights work best for moderate-reflection surfaces, labels, presence checks, and features that do not require strong directional shadows.
Best fit
- Presence and absence inspection
- Label, mark, and OCR checks on matte surfaces
- General assembly inspection
- Moderate working-distance front lighting
Likely to fail when
- Highly reflective curved metal creates glare
- Surface scratches require directional shadow
- The lens blocks too much light at short distance
Selection inputs
- Outer diameter vs lens and field of view
- Illumination angle
- Working distance
- Required wavelength
- Continuous or strobe operation
