Part 7: Machine Vision Lighting

Without good lighting your vision system will never see anything! Therefore identifying the correct lighting technique to use within an inspection solution is vital to the success on the solution. Multipix have trained staff that are experts in this field. Multipix not only have a wealth of knowledge but a huge array of lighting at our disposal. Including ranges from, LEIMAC, Moritex, Genesi, DCM, and Spectrum Illumination.

Traditional Lighting Schemes…

		Ring Light   Versatile and common lighting solution. Available as direct or indirect and with low angle options for illuminating defects on shiny surfaces. View our full range of Ring Lights…
		Back Light   Delivers broad, high-quality diffused light, providing sharp contrast to outline the shape of a component and view openings such as drilled holes. View our full range of Back Lights…
		Dome Light   Provides practical and cost effective solutions illuminating the surface of an object uniformly by reflecting 360 degrees of light. Ideal for shiny or bumpy surfaces. View our full range of Dome Lights…
		Darkfield Light   Provides 360-degree illumination from a shallow angle to ensure that the LEDs are not reflected even on shiny surfaces. Dramatically enhances the contrast of surface features such as laser-embossed, engraved marks or surface defects. View our full range of Darkfield Lights…
		Coaxial Light   Provides diffused, uniform illumination for flat specular surfaces. Can be a separate unit or integrated in suitable lenses to offer illumination within the cameras optical path. Ideal for imaging reflective surfaces, including wafers, metal surfaces, film, liquid crystal and glass. View our full range of Coaxial Lights…
		Line Light   Ideal for linescan camera applications where very intense and uniform illumination is required over a wide field of view. View our full range of Line Lights…

Beyond traditional methods there are many special lighting techniques.

The LEIMAC flat dome is a superb example of advances in lighting techniques and technology:

Another would be Infra-Red illumination: IR lighting can be used to ‘eliminate’ colour information. Or create high contrast especially for items that are difficult to view in visible light. Check out our video to see this effect in action!

Lasers

Lasers are another source of illumination that is often over-looked.

They are typically used for alignment and 3D profiling but can also be used as a source of monochromatic light.

Check out this video where the laser line is being used to enable 3D profiling in combination with a SmartRay 3D camera.
