Advanced Illumination

Advanced Illumination backlights provide an area of uniform illumination, oriented behind the object of interest, primarily for creating a part silhouette of instant contrast between dark and light. It is most useful for edge detection, part location/orientation or presence/absence, hole detection and object gauging.

Notable models include:

• Edge-lit: The BX Series Edge-lit backlights offer high brightness with low heat output. This product comes in the most common wavelengths and offers expandable sizes up to 24" by 24".
• Back-lit: The BL Series has a back-lit array of LEDs with a planar. The light features a low-profile design for flexibility in your applications and custom size and power options.
• UltraSeal IP69K: The BL245 Series are IP69K certified to withstand harsh environments like high-pressure steam and liquid immersion.
• Collimated: The CB Series is designed for precision silhouetting and supports applications like glass and plastic defect detection, thread inspection and printed circuit board (PCB) hole accuracy.

These bar lights offer both bright field and dark field illumination, depending on angle of incidence with respect to the object of interest. Because of the variety of lengths available, bar lights can also be used in replacement of Spot or Ring Lights when greater intensity is required.

Features include:

• Daisy-Chainable: EuroBrite™ bar lights offer high illumination and built-in control for strobe and continuous modes. Daisy chain up to four lights for a length of up to 48".
• High Current: MicroBrite™ and LL Series bar lights support high-current applications with a range of wavelengths and expandable sizes.
• High Dispersion: AL Series lights offer high dispersion lighting for short working distances and reflective surfaces.
• Narrow & Wide: The AL Series also features narrow and wide versions to meet illumination requirements for your application.
• IP69K: UltraSeal bar lights withstand corrosive washdown environments, high-pressure steam and liquid immersion.

Coaxial Lights provide a type of diffuse illumination, generated from an internal source. The light is then deflected downward onto the imaging plane via a 50% beamsplitter, which also allows light from the object to be collected by the camera above. Ideal for imaging highly reflective objects or where the area of inspection is obscured by shadows from its surroundings.

Advanced Illumination coaxial lights feature qualities like:

• High-current ratings
• Square, linear and spot designs
• Heat sinks and other thermal management technology

Diffuse lighting, also known as “cloudy-day illumination” provides non-directional, soft illumination that is free of shadowing. This effect is well suited for inspecting highly specular, and curved objects, but at close working distances.

• Flat Domes: FD and FX Series diffuse lights have a flat, space-saving design with illumination made for highly reflective objects.
• Domed Illuminators: A range of dome light sizes allows for inspection of rough, reflective, specular and topographic surfaces.
• Micro Sizes: Compact sizes like the extra small and small dome light save space in various applications. The small dome light also offers a three-channel, RGB configuration.
• Extra Large Sizes: The DL071 Large Area diffuse light provides illumination over an 18" square for larger workpiece applications.
• Line lights: Wide linear diffuse lights support the inspection of cylindrical and elongated objects and function well in multi-camera setups. Narrow linear lights offer precision scanning for highly reflective materials.

LED Line Lights, as opposed to linear array bar lights, employ a secondary lens to focus the light into a narrow beam, typically for short to intermediate working distances, and are mostly used in conjunction with line scan cameras.

Ai line lights offer features like:

• High and low current ratings
• Wavelength options
• Oblique designs for inspecting engraved and raised lines on a workpiece

Dark field ring lights provide illumination that is projected at a shallow angle to the imaging surface, 45 degrees or less. Typical applications include reflective flat surface defect or edge detection. Bright field ring lights provide illumination directly onto an object, at angles of incidence above 45 degrees from horizontal, creating distinct shadows or general purpose illumination depending on subjects features.

• Light & Dark Field
• Aimed & Angled LED
• Diffuse
• Large and Micro Sizes

Spot Lights are typically characterized as general-purpose illuminators. They may be used to create both bright field and dark field effects, depending on the light angle of incidence. Working distances can be short to long, depending on available intensity and beam spread. Available in large, compact and micro sizes these high intensity spot lights are beneficial when deployed in tight spaces.
