Lighting plays a major role for industrial machine vision: Not the object itself, but only the visual image of the object is checked! It follows that only homogeneous lighting conditions result in a consistent image of the same inspection object. Fluctuating light conditions are therefore to be avoided at all costs!

As the object characteristics of inspected part cannot or can only hardly be influenced, the object determines the illumination and the camera! The camera, in turn, defines the optics due to its working distance and mount, due to its data format and data rate it also determines the image acquisition card.

Only if it is possible to visualize the desired test characteristics or errors with enough contrast, these can then be evaluated with the image processing software. Usually the object is illuminated by an external light source. This principle sounds very trivial, but the practice reveals that it is one of the main difficulties of industrial machine vision to make the error in the object visible at all for the camera.

Direct frontlight illumination Surface partly very bright but overexposed, partly dark due to total reflection. Diffuse dom light illumination Surface smoothly illuminated due to homogeneous incident light. Dark field illumination Lateral edges are very bright. Scratches and dust are visible. Backlight illumination Part appears only as black silhouette. No surface information, contures ideal for measurement applications.

Pixel mappable IP65-rated LED batten produces deep, saturated, perfectly-mixed colours for wall grazing and dynamic linear washes and effects: – 15 x 10W RGBW LEDs – Mounting brackets allow fixture to be flown or floor-mounted – Rugged diecast body and touring-grade construction – Colour and white presets available via onboard menu or DMX – Silent operation with advanced fanless thermal management – Onboard library of 14 dynamic preprogrammed light shows – Custom colour mixing and adjustable white balance – Menu display backlight auto blackout – Power linking (IP65 PowerKon In/Out) – DMX or W-DMX control (W-DMX onboard)

Outdoor-rated Quad-colour (4-in-one) RGBW one-meter LED bar /  batten delivers vibrant linear colour washes and an individually controllable 15 x 1 pixel matrix.

The key role plays the light with its interaction in a functional chain of illumination, test object, filter, lens and camera:
