Ring Light
Shadow-reducing, uniform illumination for stereo microscopes, video inspection, and cleanroom QA.
Uniform Lighting Reduced Shadows Stereo Microscopy Inspection & QA
Ring lights mount around the objective to deliver even, 360° illumination directly onto the inspection area. This geometry minimizes shadows and hot spots, making it easier to detect particles, scratches, residues, and surface non-uniformity—especially during cleanroom microscopy and video inspection.
Where ring lights excel in cleanrooms
- Particle inspection: improves visibility of fibers and contamination on components, wafers, and assemblies.
- Surface defect detection: reveals micro-scratches, pits, coating defects, and haze with consistent lighting.
- Video microscopy: provides stable illumination for documentation photos and repeatable comparisons.
- Fine assembly work: reduces operator fatigue by removing uneven lighting and harsh shadows.
WHAT TO CONSIDER WHEN SELECTING A RING LIGHT
- Mount diameter: confirm inner/outer diameter matches your microscope objective housing.
- Brightness control: smooth dimming helps tune contrast for reflective, matte, and translucent surfaces.
- Color temperature: influences perceived contrast; consistent output supports repeatable inspection criteria.
- Working distance: ensure the ring light does not interfere with focus travel, sample holders, or fixturing.
