Coaxial Lights and When to Use Them
Coaxial illuminators are suitable for reflective surfaces to achieve high contrast at the edges of the object, perfect for inspecting scratches or damage on semi-gloss, glossy or reflective components and surfaces.
Coaxial lights direct light onto the object with a semi-transparent mirror.
The light reflected from the object passes through the semi-transparent mirror into the aperture of the camera; diffusely reflected light, on the other hand, radiates past the lens. This effect can be controlled by altering the distance between the camera and the object.
Coaxial light is suitable for creating high contrast at the edges of reflective objects.
Tip: This effect can be controlled via the distance from the camera to the object.
Application example: Inspection of scratches or damage on semi-gloss, glossy, or reflective components and surfaces.
