Backlighting provides an area of uniform illumination, from behind the object of interest, primarily used to create a part silhouette with definite contrast between dark and light.  Backlighting is most useful for edge detection, part location/orientation or presence/absence, hole detection and object gauging.

Advanced Illumination offers backlights in a range of styles and a range of color wavelengths or white lighting available.

Bar Lights, also called Linear Array Lights, offer both bright field and dark field illumination, depending on angle the light array is directed with respect to the object of interest. Advanced Illumination’s bar lights come in a variety of lengths, widths, and wavelengths, and with creative placement, the bar lights can useful for large area illumination, such as when used in opposing pairs or in a picture frame mounting orientation.

Coaxial Lights provide diffused 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.  Coaxial lighting is deal for imaging highly reflective objects or for when shadows obsure the area of inspection. The goal of coaxial illumination is to apply a sheet of light to the object from above and collect the results of how the light behaves, whether reflected, scattered or absorbed.

Diffuse lighting is typically provided via a dome which scatters light internally to created a diffused “cloudy day” effect. The softer light reduces the occurrence of harsh lines and shadows, but requires that the light source be close and large for the best results.

Advanced Illumination offers the typical dome shaped diffuse lighting solutions, but also offers models that are linear, and flat domes, which can provide an adequate “Cloudy Day” lighting effect at a larger range of working distances than domes. All diffuse lighting solutions are available in a range of wavelengths.

Line lighting, while linear, serves a different purpose than linear array(bar) lighting. Line lights features 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.

Advanced Illumination line lights come in a range of wavelengths and intensities.

Dark Field Lights provide illumination that is projected at a shallow angle to the imaging surface, 45 degrees or less, which is ideal for edge or defect detection. Dark field illuminators can be dedicated ring lights, or any general bar or spot light oriented at low angles of incidence, depending on defect orientation. Very low angle dark field ring lights must be deployed at close working distances to be effective.

Advanced Illumination offers dark field ring lights in a variety of sizes and wavelengths.

Bright Field Lights provide illumination directly onto an object, at angles above 45 degrees from horizontal, creating distinct shadows. This type of lighting is effective when your use requires high degrees of contrast, but may create unwanted reflections when directed at shiny or reflective materials because of the high angle of incidence. Working distances can be short to very long.

Advanced Illumination offers bright field ring lights in a variety of sizes, wavelengths, and intensities.

Spot lights are general purpose illuminators, serving different functions depending on the angle of incidence and can have a range of effects based on intensity, size, and beam spread. Small spot lights are ideal for tight spaces.

Advanced Illumination spot lights come in a variety of shapes, sizes, and wavelengths, including coaxial spot lights.
