High-angle illumination
Provides broad light from an upper angle and supports an overall view of the surface.
HYBRID LIGHTING
Reveal surface features with light from multiple directions.
HYBL-L300-P15-WH-A3
Hybrid Lighting 300 mm
This lighting unit combines high-angle, coaxial and lateral illumination. Each direction can be adjusted to suit the material, surface and feature that needs to be detected.
Tell us about the target, the feature you need to see and your current imaging conditions. We can review the lighting, camera and lens configuration together.
HOW IT WORKS
Three directions in one lighting block
High-angle illumination lights a broad area, coaxial illumination follows the camera axis, and lateral illumination emphasises edges and small height differences.
Comparing and combining these directions helps separate the feature of interest from glare, texture or background patterns.
LIGHTING MODES
Different directions reveal different features
Surface condition, height and edges reflect light differently. Adjusting each channel changes the contrast of the feature being inspected.
Coaxial illumination
Lights along the camera axis so flat areas appear bright while tilted or uneven areas appear darker.
Lateral illumination
Uses a low angle to emphasise reflections from scratches, chips, edges and small height differences.
High angle
Coaxial
Lateral
VISIBILITY
Keep the feature you need and suppress distracting texture
By adjusting the balance between lighting directions, imaging can be tuned either to reduce hairline texture or to emphasise it. The aim is a repeatable image in which the inspection feature remains visible.
APPLICATIONS
Typical inspection targets
Reflective metals and mirror surfaces
Explore conditions for scratches that are easily hidden by strong directional reflections.
Fine scratches and abrasions
Designed with high-resolution line-camera imaging in mind.
Targets with significant depth
High output supports a smaller lens aperture and a greater depth of field where appropriate.

Lighting
Why illuminate from multiple angles? — distinguish scratches from reflections
The same scratch can look different under different lighting directions. Compare each direction to separate surface texture from the feature you need to inspect.
