High intensity is not a substitute for proper geometry. You likely need to change the angle of incidence or use a diffuser to eliminate specular reflections.

What are Machine Vision Lighting components?
Machine vision lighting is critical for maximizing feature contrast in automated inspection. Success depends on matching the light geometry—such as ring, bar, or dome—to the surface texture and material of the target to minimize glare and highlight defects.
How to Choose Machine Vision Lighting Components
Selecting the right light is more important than camera resolution. Follow these steps to ensure high-contrast image acquisition.
Geometry Selection
Use ring lights for uniform illumination, bar lights for grazing angles, and dome lights for diffuse, shadow-free results on shiny surfaces.
Wavelength Matching
Use monochromatic light (e.g., blue or red) with matching bandpass filters to eliminate ambient interference and improve contrast.
Strobe Control
High-speed lines require strobe lighting to freeze motion; ensure your controller supports the necessary trigger pulse width and frequency.
Intensity Requirements
Calculate the required lux based on camera exposure time and lens aperture to avoid motion blur or signal-to-noise issues.
Environmental Rating
Verify IP ratings if the lighting is deployed in washdown or high-particulate industrial environments.
